See `FragmentsWithSharedElements.kt` in the test application for examples of how to use `FragmentSharedElements` +* Added `acceptFromFlow` as a `NavigationContainerFilter` for use on screens that build managed flows using `registerForFlowResult`. This filter will cause the `NavigationContainer` to only accept instructions that have been created as part a managed flow, and will reject instructions that are not part of a managed flow. +* Removed `isAnimating` from `ComposableNavigationContainer`, as it was unused internally, did not appear to be useful for external use cases, and was complicating Compose animation code. If this functionality *was* important to your use case, please create a Github issue to discuss your use case. +* Removed the requirement to provide a SavedStateHandle to `registerForFlowResult`. This should not affect any existing code, but if you were passing a SavedStateHandle to `registerForFlowResult`, you can now remove this parameter. + * NavigationHandles now have access to a SavedStateHandle internally, which removes the requirement to pass this through to `registerForFlowResult` +* Added `managedFlowDestination` as a way to create a managed flow as a standalone destination + * `managedFlowDestination` works in the same way you'd use `registerForFlowResult` to create a managed flow, but allows you to define the flow as a standalone destination that can be pushed or presented from other destinations, without the need to define a ViewModel and regular destination for the flow. + * `managedFlowDestination` is currently marked as an `@ExperimentalEnroApi`, and may be subject to change in future versions of Enro. + * For an example of a `managedFlowDestination`, see `dev.enro.tests.application.managedflow.UserInformationFlow` in the test application + +* ⚠️ Updated result channel identifiers in preparation for Kotlin 2.0 ⚠️ + * Kotlin 2.0 changes the way that lambdas are compiled, which has implications for `registerForNavigationResult` and how result channels are uniquely identified. Activites, Fragments, Composables and ViewModels that use `by registerForNavigationResult` directly will not be affected by this change. However, if you are creating result channels inside of other objects, such as delegates, helper objects, or extension functions, you should verify that these cases continue to work as expected. It is not expected that there will be issues, but if this does result in bugs in your application, please raise them on the Enro GitHub repository. + +* ⚠️ Updated NavigationContainer handling of NavigationInstructionFilter ⚠️ + * In versions of Enro before 2.8.0, NavigationContainers would always accept destinations that were presented (`NavigationInstruction.Present(...)`, `navigationHandle.present(...)`, etc), and would only enforce their instructionFilter for pushed instructions (`NavigationInstruction.Push(...)`, `navigationHandle.push(...)`, etc). This is no longer the default behavior, and NavigationContainers will apply their instructionFilter to all instructions. + * This behavior can be reverted to the previous behavior by setting `useLegacyContainerPresentBehavior` when creating a NavigationController for your application using `createNavigationController`. + * `useLegacyContainerPresentBehavior` will be removed in a future version of Enro, and it is recommended that you update your NavigationContainers to explicitly declare their instructionFilter for all instructions, not just pushed instructions. + +## 2.7.0 +* ⚠️ Updated to androidx.lifecycle 2.8.1 ⚠️ + * There are breaking changes introduced in androidx.lifecycle 2.8.0; if you use Enro 2.7.0, you must upgrade your project to androidx.lifecycle 2.8+, otherwise you are likely to encounter runtime errors + +## 2.6.0 +* Added `isManuallyStarted` to the `registerForFlowResult` API, which allows for the flow to be started manually with a call to `update` rather than performing this automatically when the flow is created. +* Added `async` to `NavigationFlowScope`, which allows the execution of suspending lambdas as part of the steps in a flow. + +## 2.5.0 +* Added `update` to the public API for `NavigationFlow`, as this is required for some use cases where the flow needs to be updated after changes in external state which may affect the logic of the flow. This function was previously named `next`, and removed from the public API in 2.4.0. +* Moved `NavigationContext.getViewModel` and `requireViewModel` extensions to the `dev.enro.viewmodel` package. +* Added `NavigationResultScope` as a receiver for all registerForNavigationResult calls, to allow for more advanced handling of results and inspection of the instruction and navigation key that was used to open the result request. + +## 2.4.1 +* Added `EnroBackConfiguration`, which can be set when creating a `NavigationController`. This controls how Enro handles back presses. + * EnroBackConfiguration.Default will use the behavior that has been standard in Enro until this point + * EnroBackConfiguration.Manual disables all back handling via Enro, and allows developers to set their own back pressed handling for individual destinations + * EnroBackConfiguration.Predictive is experimental, but adds support for predictive back gestures and animations. This is not yet fully implemented, and is not recommended for production use. Once this is stabilised, EnroBackNavigation.Default will be renamed to EnroBackNavigation.Legacy, and EnroBackNavigation.Predictive will become the default. +* Removed `ContainerRegistrationStrategy` from the "core" `rememberNavigationContainer` methods, to stop the requirement to opt-in for `AdvancedEnroApi` when using the standard `rememberNavigationContainer` APIs. This was introduced accidentally with 2.4.0. +* Added `EmbeddedNavigationDestination` as an experimental API, which allows a `NavigationKey.SupportsPush` to be rendered as an embedded destination within another Composable. + +## 2.4.0 +* Updated dependency versions +* Added `instruction` property directly to `NavigationContext`, to provide easy access to the instruction +* Added extensions `getViewModel` and `requireViewModel` to `NavigationContext` to access `ViewModels` directly from a context reference +* Added extensions for `findContext` and `findActiveContext` to `NavigationContext` to allow for finding other NavigationContexts from a context reference +* Updated `NavigationContainer` to add `getChildContext` which allows finding specific Active/ActivePushed/ActivePresented/Specific contexts from a container reference +* Added `instruction` property to `NavigationContext`, and marked `NavigationContext` as `@AdvancedEnroApi` +* Updated `NavigationContext` and `NavigationHandle` to bind each other to allow for easier access to the other from either reference, and to ensure the lazy references are still available while the context is being referenced +* Updated result handling for forwarding results to fix several bugs and improve behaviour (including correctly handling forwarded results through Activities) +* Added `transient` configuration to NavigationFlow steps, which allows a step to only be re-executed if it's dependencies have changed +* Added `navigationFlowReference` as a parcealble object which can be passed to NavigationKeys, and then later used to retrieve the parent navigation flow +* Prevent more than one registerForNavigationResult from occurring within the context of a single NavigationHandle +* Remove `next` from the public API of NavigationFlow, in favour of doing this automatically on creation of the flow +* Added a new version of `OverrideNavigationAnimations`, which provides a way to override animations and receive an `AnimatedVisibilityScope` which is useful for shared element transitions. + +## 2.3.0 +* Updated NavigationFlow to return from `next` after `onCompleted` is called, rather than continuing to set the backstack from the flow +* Updated NavigationContainer to take a `filter` of type NavigationContainerFilter instead of an `accept: (NavigationKey) -> Boolean` lambda. This allows for more advanced filtering of NavigationKeys, and this API will likely be expanded in the future. + * For containers that pass an argument of `accept = { }` a quick replacement is `filter = acceptKey { }`, which will have the same behavior. +* Updated EmptyBehavior to use `requestClose` for the CloseParent behavior, and added ForceCloseParent as a method for retaining the old behavior which will close the parent of the container without going through that destination's `onRequestClose`. +* Fixed a bug with nested Composable NavigationContainers and the active container being changed while the parent Composable was not active. + +## 2.2.0 +* Removed NavigationAnimationOverrideBuilder methods that did not take a `returnEntering` or `returnExiting` parameter, in favour of defaulting these parameters to `entering` and `exiting` respectively. If you do not want to override return animations, you are able to pass null for these parameters to override the defaults. +* Removed default `EmptyBehavior` parameter for `rememberNavigationContainer`; an explicit EmptyBehaviour is now required. The default was previously `EmptyBehavior.AllowEmpty`, and usages of `rememberNavigationContainer` that were relying on this default parameter should be updated to pass this explicitly. +* Fixed a bug with `EnroTestRule` incorrectly capturing back presses for DialogFragments that are not bound into Enro + +## 2.1.1 +* Fixed a bug with `EnroTestRule`/`runEnroTest` that would cause instrumented `androidTest` tests to fail when including both tests that use `EnroTestRule`/`runEnroTest` and tests that do not in the same test suite + +## 2.1.0 +* Update to Compose 1.5.x +* Moved Activity/Fragment integrations out of the core of Enro and into independent plugins (which are still installed by default) +* Fixed a bug with NavigationResult channels not using the correct result channel id in some cases + +## 2.0.0 +Enro 2.0.0 introduces some important changes from the 1.x.x branch: +* Compose destinations are now stable +* The BottomSheetDestination and DialogDestination interfaces have been deprecated + * Replace these with using the Composables named BottomSheetDestination and DialogDestination + * See [DialogDestination.kt](example%2Fsrc%2Fmain%2Fjava%2Fdev%2Fenro%2Fexample%2Fdestinations%2Fcompose%2FDialogComposable.kt) + * See [BottomSheetComposable.kt](example%2Fsrc%2Fmain%2Fjava%2Fdev%2Fenro%2Fexample%2Fdestinations%2Fcompose%2FBottomSheetComposable.kt) +* Synthetic destinations can be defined as properties + * See [SimpleMessage.kt](example%2Fsrc%2Fmain%2Fjava%2Fdev%2Fenro%2Fexample%2Fdestinations%2Fsynthetic%2FSimpleMessage.kt) +* Forward/Replace instructions have been deprecated + * Usages of Forward should be replaced with a mix of Push and/or Present + * See https://enro.dev/docs/frequently-asked-questions.html for an explanation of Push vs. Present + * Usages of Replace should be replaced with a `push/present` followed by a `close` +* Both Composables and Fragments now use a shared NavigationContainer type to host navigation + * See [MainActivity.kt](example%2Fsrc%2Fmain%2Fjava%2Fdev%2Fenro%2Fexample%2FMainActivity.kt) or [RootFragment.kt](example%2Fsrc%2Fmain%2Fjava%2Fdev%2Fenro%2Fexample%2FRootFragment.kt) for an example of Fragment containers + * See [ListDetailComposable.kt](example%2Fsrc%2Fmain%2Fjava%2Fdev%2Fenro%2Fexample%2Fdestinations%2Flistdetail%2Fcompose%2FListDetailComposable.kt) for an example of Composable containers + * The `OnContainer` Navigation Instruction has been added, which allows direct backstack manipulation of NavigationContainers + * NavigationContainers allow advanced functionality such as interceptors and animation overrides +* `deliverResultFromPush`/`deliverResultFromPresent` are new extension functions which allow a screen to delegate it's result to another screen + * See the [embedded flow](example%2Fsrc%2Fmain%2Fjava%2Fdev%2Fenro%2Fexample%2Fdestinations%2Fresult%2Fflow%2Fembedded) for examples +* `activityResultDestination` is a new function which allows ActivityResultContracts to be used directly as destinations + * See [ActivityResults.kt](example%2Fsrc%2Fmain%2Fjava%2Fdev%2Fenro%2Fexample%2Fdestinations%2Factivity%2FActivityResults.kt) \ No newline at end of file diff --git a/README.md b/README.md index 485834ce..5d011a22 100644 --- a/README.md +++ b/README.md @@ -1,353 +1,167 @@ [![Maven Central](https://img.shields.io/maven-central/v/dev.enro/enro.svg?label=Maven%20Central)](https://search.maven.org/search?q=g:%22dev.enro%22) +> **Note** +> +> Please see the [CHANGELOG](./CHANGELOG.md) to understand the latest changes in Enro # Enro 🗺️ -A simple navigation library for Android +### [enro.dev](https://enro.dev) -*"The novices’ eyes followed the wriggling path up from the well as it swept a great meandering arc around the hillside.

+# Introduction +This introduction is designed to give a brief overview of how Enro works. It doesn't contain all the information you might need to know to get Enro installed in an application, or provide specific details about each of the topics covered. For this information please refer to the other documentation, such as: +* [Installing Enro](https://enro.dev/docs/installing-enro.html) +* [Navigation Keys](https://enro.dev/docs/navigation-keys.html) +* [FAQ](https://enro.dev/docs/frequently-asked-questions.html) -#### 1. Define your NavigationKeys +## NavigationKeys +Building a screen using Enro begins with defining a `NavigationKey`. A `NavigationKey` can be thought of like the function signature or interface for a screen. Just like a function signature, a `NavigationKey` represents a contract. By invoking the contract, and providing the requested parameters, an action will occur and you may (or may not) receive a result. + +Here's an example of two `NavigationKey`s that you might find in an Enro application: ```kotlin -@Parcelize -data class MyListKey(val listType: String): NavigationKey @Parcelize -data class MyDetailKey(val itemId: String, val isReadOnly): NavigationKey +data class ShowUserProfile( + val userId: UserId +) : NavigationKey.SupportsPush @Parcelize -data class MyComposeKey(val name: String): NavigationKey +data class SelectDate( + val minDate: LocalDate? = null, + val maxDate: LocalDate? = null, +) : NavigationKey.SupportsPresent.WithResult + ``` -#### 2. Define your NavigationDestinations +If you think of the `NavigationKey`s as function signatures, they could look something like this: ```kotlin -@NavigationDestination(MyListKey::class) -class ListFragment : Fragment() -@NavigationDestination(MyDetailKey::class) -class DetailActivity : AppCompatActivity() +fun showUserProfile(userId: UserId): Unit +fun selectDate(minDate: LocalDate? = null, maxDate: LocalDate? = null): LocalDate -@Composable -@ExperimentalComposableDestination -@NavigationDestination(MyComposeKey::class) -fun MyComposableScreen() { } ``` -#### 3. Annotate your Application as a NavigationComponent, and implement the NavigationApplication interface -```kotlin -@NavigationComponent -class MyApplication : Application(), NavigationApplication { - override val navigationController = navigationController() -} -``` +## NavigationHandles +Once you've defined the `NavigationKey` for a screen, you'll want to use it. In any Activity, Fragment or Composable, you will be able to get access to a `NavigationHandle`, which allows you to perform navigation. The syntax is slightly different for each type of screen. -#### 4. Navigate! +### In a Fragment or Activity: ```kotlin -@NavigationDestination(MyListKey::class) -class ListFragment : ListFragment() { - val navigation by navigationHandle() - - fun onViewCreated(view: View, savedInstanceState: Bundle?) { - val listType = navigation.key.listType - view.findViewById(R.id.list_title_text).text = "List: $listType" - } - - fun onListItemSelected(selectedId: String) { - val key = MyDetailKey(itemId = selectedId) - navigation.forward(key) - } -} -@Composable -@ExperimentalComposableDestination -@NavigationDestination(MyComposeKey::class) -fun MyComposableScreen() { - val navigation = navigationHandle() - - Button( - content = { Text("Hello, ${navigation.key}") }, - onClick = { - navigation.forward(MyListKey(...)) - } - ) +class ExampleFragment : Fragment() { + val selectDate by registerForNavigationResult { selectedDate: LocalDate -> + /* do something! */ + } + + fun onSelectDateButtonPressed() = selectDate.present( + SelectDate(maxDate = LocalDate.now()) + ) + + fun onProfileButtonPressed() { + getNavigationHandle().push( + ShowUserProfile(userId = /* ... */) + ) + } } ``` -## Applications using Enro -

- -## FAQ -#### Minimum SDK Version -Enro supports a minimum SDK version of 16. However, support for SDK 16 was only recently added and targetting any SDK below 21 should be considered experimental. If you experience issues running on an SDK below 21, please report a GitHub issue. - -#### How well does Enro work alongside "normal" Android Activity/Fragment navigation? -Enro is designed to integrate well with Android's default navigation. It's easy to manually open a Fragment or Activity as if Enro itself had performed the navigation. Create a NavigationInstruction object that represents the navigation, and then add it to the arguments of a Fragment, or the Intent for an Activity, and then open the Fragment/Activity as you normally would. - -Example: -```kotlin -val instruction = NavigationInstruction.Forward( - navigationKey = MyNavigationKey(...) -) -val intent = Intent(this, MyActivity::class).addOpenInstruction(instruction) -startActivity(intent) -``` - -#### How does Enro decide if a Fragment, or the Activity should receive a back button press? -Enro considers the primaryNavigationFragment to be the "active" navigation target, or the current Activity if there is no primaryNavigationFragment. In a nested Fragment situation, the primaryNavigationFragment of the primaryNavigationFragment of the ... is considered "active". - -#### What kind of navigation instructions does Enro support? -Enro supports three navigation instructions: `forward`, `replace` and `replaceRoot`. - -If the current navigation stack is `A -> B -> C ->` then: -`forward(D)` = `A -> B -> C -> D ->` -`replace(D)` = `A -> B -> D ->` -`replaceRoot(D)` = `D ->` - -Enro supports multiple arguments to these instructions. -`forward(X, Y, Z)` = `A -> B -> C -> X -> Y -> Z ->` -`replace(X, Y, Z)` = `A -> B -> X -> Y -> Z ->` -`replaceRoot(X, Y, Z)` = `X -> Y -> Z ->` - -#### How does Enro support Activities navigating to Fragments? -When an Activity executes a navigation instruction that resolves to a Fragment, one of two things will happen: -1. The Activity's navigator defines a "container" that accepts the Fragment's type, in which case, the Fragment will be opened into the container view defined by that container. -2. The Activity's navigation **does not** define a fragment host that acccepts the Fragment's type, in which case, the Fragment will be opened into a new, full screen Activity. - -#### How do I deal with Activity results? -Enro supports any NavigationKey/NavigationDestination providing a result. Instead of implementing the NavigationKey interface on the NavigationKey that provides the result, implement NavigationKey.WithResult where T is the type of the result. Once you're ready to navigate to that NavigationKey and consume a result, you'll want to call "registerForNavigationResult" in your Fragment/Activity/ViewModel. This API is very similar to the AndroidX Activity 1.2.0 ActivityResultLauncher. - -Example: +### In a Composable: ```kotlin -@Parcelize -class RequestDataKey(...) : NavigationKey.WithResult() -@NavigationDestination(RequestDataKey::class) -class MyResultActivity : AppCompatActivity() { - val navigation by navigationHandle() - - fun onSendResultButtonClicked() { - navigation.closeWithResult(false) - } +@Composable +fun ExampleComposable() { + val navigation = navigationHandle() + val selectDate = registerForNavigationResult { selectedDate: LocalDate -> + /* do something! */ + } + + Button(onClick = { + selectDate.present( + SelectDate(maxDate = LocalDate.now()) + ) + }) { /* ... */ } + + Button(onClick = { + navigation.push( + ShowUserProfile(userId = /* ... */) + ) + }) { /* ... */ } } -@NavigationDestination(...) -class MyActivity : AppCompatActivity() { - val requestData by registerForNavigationResult { - // do something! - } - - fun onRequestDataButtonClicked() { - requestData.open(RequestDataKey(/*arguments*/)) - } -} ``` -#### How do I do Master/Detail navigation -Enro has a built in component for this. If you want to build something more complex than what the built-in component provides, you'll be able to use the built-in component as a reference/starting point, as it is built purely on Enro's public API - -#### How do I handle multiple backstacks on each page of a BottomNavigationView? -Enro has a built in component for this. If you want to build something more complex than what the built-in component provides, you'll be able to use the built-in component as a reference/starting point, as it is built purely on Enro's public API +## NavigationDestinations +You might have noticed that we've defined our `ExampleFragment` and `ExampleComposable` in the example above before we've even begun to think about how we're going to implement the `ShowUserProfile` and `SelectDate` destinations. That's because implementing a `NavigationDestination` in Enro is the least interesting part of the process. All you need to do to make this application complete is to build an Activity, Fragment or Composable, and mark it as the `NavigationDestination` for a particular `NavigationKey`. -#### I'd like to do shared element transitions, or do something special when navigating between certain screens -Enro allows you to define "NavigationExecutors" as overrides for the default behaviour, which handle these situations. +The recommended approach to mark an Activity, Fragment or Composable as a `NavigationDestination` is to use the Enro annotation processor and the `@NavigationDestination` annotation. -There will be an example project that shows how this all works in the future, but for now, here's a basic explanation: -1. A NavigationExecutor is typed for a "From", an "Opens", and a NavigationKey type. -2. Enro performs navigation on a "NavigationContext", which is basically either a Fragment or a FragmentActivity -3. A NavigationExecutor defines two methods - * `open`, which takes a NavigationContext of the "From" type, a Navigator for the "Opens" type, and a NavigationInstruction (i.e. the From context is attempting to open the Navigator with the input NavigationInstruction) - * `close`, which takes a NavigationContext of the "Opens" type (i.e. you're closing what you've already opened) -4. By creating a NavigationExecutor between two specific screens and registering this with the NavigationController, you're able to override the default navigation behaviour (although you're still able to call back to the DefaultActivityExecutor or DefaultFragmentExecutor if you need to) -5. See the method in NavigationControllerBuilder for `override` -6. When a NavigationContext decides what NavigationExecutor to execute an instruction on, Enro will look at the NavigationContext originating the NavigationInstruction and then walk up toward's it's root NavigationContext (i.e. a Fragment will check itself, then its parent Fragment, and then that parent Fragment's Activity), checking for an appropriate override along the way. If it finds no override, the default will be used. NavigationContexts that are the children of the current NavigationContext will not be searched, only the parents. - -Example: +### In a Fragment or Activity: ```kotlin -// This override will place the "DetailFragment" into the container R.id.detail, -// and when it's closed, will set whatever Fragment is in the R.id.master container as the primary navigation fragment -override( - launch = { - val fragment = DetailFragment().addOpenInstruction(it.instruction) - it.fromContext.childFragmentManager.beginTransaction() - .replace(R.id.detail, fragment) - .setPrimaryNavigationFragment(fragment) - .commitNow() - }, - close = { context -> - context.fragment.parentFragmentManager.beginTransaction() - .remove(context.fragment) - .setPrimaryNavigationFragment(context.parentActivity.supportFragmentManager.findFragmentById(R.id.master)) - .commitNow() - } -) -``` - -#### I'd like to add a custom animation (using an override) for a @Composable @NavigationDestination -Unlike Activities and Fragments, when you want to write an override for a @Composable @NavigationDestination (particularly to specify custom animations), you don't have a class to reference in the To or From type arguments to the `override()` function. At first glance, it may appear that it is not possible to create an override for a @Composable @NavigationDestination. -However, when you define a @Composable @NavigationDestination, Enro generates a class, called `Destination`. This class can be used when specifying overrides for @Composable @NavigationDestinations. - -Example: -```kotlin -val navigationController = navigationController { - /** - * This example assumes you have a @Composable function that is also a @NavigationDestination, and that the name - * of the @Composable function is `MyComposableScreen`. - * - * This example will set both the open and close animations for this screen to be the default "no animation" animation - * that Enro provides. - */ - override { - animation { DefaultAnimations.none } - closeAnimation { DefaultAnimations.none } - } +@NavigationDestination(ShowUserProfile::class) +class ProfileFragment : Fragment { + // providing a type to `by navigationHandle()` gives you access to the NavigationKey + // used to open this destination, and you can use this to read the + // arguments for the destination + val navigation by navigationHandle() } -``` - -Please note, that the `Destination` is a generated class, and will not be available until you've compiled the project at least once since defining your @Composable @NavigationDestination (similar to how Dagger generates Components). - -#### My Activity crashes on launch, what's going on?! -It's possible for an Activity to be launched from multiple places. Most of these can be controlled by Enro, but some of them cannot. For example, an Activity that's declared in the manifest as a MAIN/LAUNCHER Activity might be launched by the Android operating system when the user opens your application for the first time. Because Enro hasn't launched the Activity, it's not going to know what the NavigationKey for that Activity is, and won't be able to read it from the Activity's intent. -Luckily, there's an easy solution! When you declare an Activty or Fragment, you are able to do a small amount of configuration inside the `navigationHandle` block using the `defaultKey` method. This method takes a `NavigationKey` as an argument, and if the Fragment or Activity is opened without being passed a `NavigationKey` as part of its arguments, the value passed will be treated as the `NavigationKey`. This could occur because of an Activity being launched via a MAIN/LAUNCHER intent filter, via a standard `Intent`, or via a `Fragment` being added directly to a `FragmentManager` without any `NavigationInstruction` being applied. In other words, any situation where Enro is not used to launch the Activity or Fragment. - -Example: -```kotlin -@Parcelize -class MainKey(isDefaultKey: Boolean = false) : NavigationKey - -@NavigationDestination(MainKey::class) -class MainActivity : AppCompatActivity() { - private val navigation by navigationHandle { - defaultKey( - MainKey(isDefaultKey = true) - ) - } -} ``` -## Why would I want to use Enro? -#### Support the navigation requirements of large multi-module Applications, while allowing flexibility to define rich transitions between specific destinations -A multi-module application has different requirements to a single-module application. Individual modules will define Activities and Fragments, and other modules will want to navigate to these Activities and Fragments. By detatching the NavigationKeys from the destinations themselves, this allows NavigationKeys to be defined in a common/shared module which all other modules depend on. Any module is then able to navigate to another by using one of the NavigationKeys, without knowing about the Activity or Fragment that it is going to. FeatureOneActivity and FeatureTwoActivity don't know about each other, but they both know that FeatureOneKey and FeatureTwoKey exist. A simple version of this solution can be created in less than 20 lines of code. - -However, truly beautiful navigation requires knowledge of both the originator and the destination. Material design's shared element transitions are an example of this. If FeatureOneActivity and FeatureTwoActivity don't know about each other, how can they collaborate on a shared element transition? Enro allows transitions between two navigation destinations to be overridden for that specific case, meaning that FeatureOneActivity and FeatureTwoActivity might know nothing about each other, but the application that uses them will be able to define a navigation override that adds shared element transitions between the two. - -#### Allow navigation to be triggered at the ViewModel layer of an Application -Enro provides a custom extension function similar to AndroidX's `by viewModels()`, called `by enroViewModels()`, which works in the exact same way. However, when you use `by enroViewModels()` to construct a ViewModel, you are able to use a `by navigationHandle()` statement within your ViewModel. This `NavigationHandle` works in the exact same way as an Activity or Fragment's `NavigationHandle`, and can be used in the exact same way. - -This means that your ViewModel can be put in charge of the flow through your Application, rather than needing to use a `LiveData()` (or similar) in your ViewModel. When we use things like `LiveData()` we are able to test the ViewModel's intent to navigate, but there's still the reliance on the Activity/Fragment implementing the response to the navigation event correctly. In the case of retrieving a result from another screen, this gap grows even wider, and there becomes an invisible contract between the ViewModel and Activity/Fragment: The ViewModel expects that if it sets a particular `NavigationEvent` in the `LiveData`, that the Activity/Fragment will navigate to the correct place, and then once the navigation has been successful and a result has been returned, that the Activity/Fragment will call the correct method on the ViewModel to provide the result. This invisible contract results in extra boilerplate "wiring" code, and a gap for bugs to slip through. Instead, using Enro's ViewModel integration, you allow your ViewModel to be precise and clear about it's intention, and about how to handle a result. - -## Experimental Compose Support -The most recent version of Enro (1.4.0-beta04) adds experimental support for directly marking `@Composable` functions as Navigation Destinations. - -To support a Composable destination, you will need to add both an `@NavigationDestination` annotation, and a `@ExperimentalComposableDestination` annotation. Once the Composable support moves from the "experimental" stage into a stable state, the `@ExperimentalComposableDestination` annotation will be removed. - -Here is an example of a Composable function being used as a NavigationDestination: +### In a Composable: ```kotlin + @Composable -@ExperimentalComposableDestination -@NavigationDestination(MyComposeKey::class) -fun MyComposableScreen() { - val navigation = navigationHandle() - - Button( - content = { Text("Hello, ${navigation.key}") }, - onClick = { - navigation.forward(MyListKey(...)) - } - ) +@NavigationDestination(SelectDate::class) +fun SelectDateComposable() { + // providing a type to `navigationHandle()` gives you access to the NavigationKey + // used to open this destination, and you can use this to read the + // arguments for the destination + val navigation = navigationHandle() + // ... + Button(onClick = { + navigation.closeWithResult( /* pass a local date here to return that as a result */ ) + }) { /* ... */ } } -``` -#### Nested Composables -Enro's Composable support is based around the idea of an "EnroContainer" Composable, which can be added to a Fragment, Activity or another Composable. The EnroContainer works much like a FrameLayout being used as a container for Fragments. - -Here is an example of creating a Composable that supports nested Composable navigation in Enro: +``` +### Without annotation processing: +If you'd prefer to avoid annotation processing, you can use a DSL to define these bindings when creating your application (see [here]() for more information): ```kotlin -@Composable -@ExperimentalComposableDestination -@NavigationDestination(MyComposeKey::class) -fun MyNestedComposableScreen() { - val navigation = navigationHandle() - val containerController = rememberEnroContainerController( - accept = { it is NestedComposeKey } - ) - - Column { - EnroContainer( - controller = containerController - ) - Button( - content = { Text("Open Nested") }, - onClick = { - navigation.forward(NestedComposeKey()) - } - ) - } + +// this needs to be registered with your application +val exampleNavigationComponent = createNavigationComponent { + fragmentDestination() + composableDestination { SelectDateComposable() } } -@Composable -@ExperimentalComposableDestination -@NavigationDestination(NestedComposeKey::class) -fun NestedComposableScreen() = Text("Nested Screen!") ``` -In the example above, we have defined an Enro Container Controller which will accept Navigation Keys of type "NestedComposeKey". When the user clicks on the button "Open Nested", we execute a forward instruction to a NestedComposeKey. Because there is an available container which accepts NestedComposeKey instructions, the Composable for the NestedComposeKey (NestedComposableScreen in the example above) will be placed inside the EnroContainer defined in MyNestedComposableScreen. - -EnroContainerControllers can be configured to have some instructions pre-launched as their initial state, can be configured to accept some/all/no keys, and can be configured with an "EmptyBehavior" which defines what will happen when the container becomes empty due to a close action. The default close behavior is "AllowEmpty", but this can be set to "CloseParent", which will pass the close instruction up to the Container's parent, or "Action", which will allow any custom action to occur when the container becomes empty. - -#### Dialog and BottomSheet support -Composable functions declared as NavigationDestinations can be used as Dialog or ModalBottomSheet type destinations. To do this, make the Composable function an extension function on either `DialogDestination` or `BottomSheetDestination`. This will cause the Composable to be launched as a dialog, escaping the current navigation context of the screen. +# Applications using Enro +
