Quick Start

All packages whose names are prefixed with flutter_ume_kit_ are function plug-ins of UME, and users can access them according to demand

1. Edit pubspec.yaml, and add dependencies.

   ↓ Null-safety version, compatible with Flutter 2.x

   dev_dependencies: # Don't use UME in release mode
     flutter_ume: ^0.3.0+1
     flutter_ume_kit_ui: ^0.3.0+1
     flutter_ume_kit_device: ^0.3.0
     flutter_ume_kit_perf: ^0.3.0
     flutter_ume_kit_show_code: ^0.3.0
     flutter_ume_kit_console: ^0.3.0
     flutter_ume_kit_dio: ^0.3.0

   ↓ Non-null-safety version, compatible with Flutter 1.x

   dev_dependencies: # Don't use UME in release mode
     flutter_ume: ^0.1.1
     flutter_ume_kit_ui: ^0.1.1.1
     flutter_ume_kit_device: ^0.1.1
     flutter_ume_kit_perf: ^0.1.1
     flutter_ume_kit_show_code: ^0.1.1
     flutter_ume_kit_console: ^0.1.1 

2. Run flutter pub get

3. Import packages

   import 'package:flutter_ume/flutter_ume.dart'; // UME framework
   import 'package:flutter_ume_kit_ui/flutter_ume_kit_ui.dart'; // UI kits
   import 'package:flutter_ume_kit_perf/flutter_ume_kit_perf.dart'; // Performance kits
   import 'package:flutter_ume_kit_show_code/flutter_ume_kit_show_code.dart'; // Show Code
   import 'package:flutter_ume_kit_device/flutter_ume_kit_device.dart'; // Device info
   import 'package:flutter_ume_kit_console/flutter_ume_kit_console.dart'; // Show debugPrint
   import 'package:flutter_ume_kit_dio/flutter_ume_kit_dio.dart'; // Dio Inspector

4. Edit main method of your app, register plugin kits and initial UME

   void main() {
     if (kDebugMode) {
       PluginManager.instance                                 // Register plugin kits
         ..register(WidgetInfoInspector())
         ..register(WidgetDetailInspector())
         ..register(ColorSucker())
         ..register(AlignRuler())
         ..register(ColorPicker())                            // New feature
         ..register(TouchIndicator())                         // New feature
         ..register(Performance())
         ..register(ShowCode())
         ..register(MemoryInfoPage())
         ..register(CpuInfoPage())
         ..register(DeviceInfoPanel())
         ..register(Console())
         ..register(DioInspector(dio: dio));                  // Pass in your Dio instance
       // After flutter_ume 0.3.0
       runApp(UMEWidget(child: MyApp(), enable: true));
       // Before flutter_ume 0.3.0
       runApp(injectUMEWidget(child: MyApp(), enable: true));
     } else {
       runApp(MyApp());
     }
   }

5. flutter run for running or flutter build apk --debug、flutter build ios --debug for building productions.

Some functions rely on VM Service, and additional parameters need to be added for local operation to ensure that it can connect to the VM Service.

Flutter 2.0.x, 2.2.x and other versions run on real devices, flutter run needs to add the --disable-dds parameter. After Pull Request #80900 merging, --disable-dds was renamed to --no-dds.

IMPORTANT

From 0.1.1/0.2.1 version，we don't need set useRootNavigator: false. The following section only applies to versions before version 0.1.1/0.2.1 .

Since UME manages the routing stack at the top level, methods such as showDialog use rootNavigator to pop up by default, therefore must pass in the parameter useRootNavigator: false in showDialog, showGeneralDialog and other 'show dialog' methods to avoid navigator errors.

showDialog(
  context: context,
  builder: (ctx) => AlertDialog(
        title: const Text('Dialog'),
        actions: <Widget>[
          TextButton(
              onPressed: () => Navigator.pop(context),
              child: const Text('OK'))
        ],
      ),
  useRootNavigator: false); // <===== It's very IMPORTANT!

Develop plugin kits for UME

UME plugins are located in the ./kits directory, and each one is a package. You can refer to the example in ./custom_plugin_example about this chapter.

1. Run flutter create -t package custom_plugin to create your custom plugin kit, it could be package or plugin.

2. Edit pubspec.yaml of the custom plugin kit to add UME framework dependency.

   dependencies:
     flutter_ume: '>=0.3.0 <0.4.0'

3. Create the class of the plugin kit which should implement Pluggable.

   import 'package:flutter_ume/flutter_ume.dart';
   
   class CustomPlugin implements Pluggable {
     CustomPlugin({Key key});
   
     @override
     Widget buildWidget(BuildContext context) => Container(
       color: Colors.white
       width: 100,
       height: 100,
       child: Center(
         child: Text('Custom Plugin')
       ),
     ); // The panel of the plugin kit
   
     @override
     String get name => 'CustomPlugin'; // The name of the plugin kit
   
     @override
     String get displayName => 'CustomPlugin';
   
     @override
     void onTrigger() {} // Call when tap the icon of plugin kit
   
     @override
     ImageProvider<Object> get iconImageProvider => NetworkImage('url'); // The icon image of the plugin kit
   }

4. Use your custom plugin kit in project

   1. Edit pubspec.yaml of host app project to add custom_plugin dependency.

      dev_dependencies:
        custom_plugin:
          path: path/to/custom_plugin

   2. Run flutter pub get

   3. Import package

      import 'package:custom_plugin/custom_plugin.dart';

5. Edit main method of your app, register your custom_plugin plugin kit

   if (kDebugMode) {
     PluginManager.instance
       ..register(CustomPlugin());
     runApp(
       UMEWidget(
         child: MyApp(), 
         enable: true
       )
     );
   } else {
     runApp(MyApp());
   }

6. Run your app

Access the nested widget debug kits quickly

We introduce the PluggableWithNestedWidget from 0.3.0. It is used to insert nested Widgets in the Widget tree and quickly access embedded kits with nested widget.

For more details, see ./kits/flutter_ume_kit_ui/lib/components/color_picker/color_picker.dart and ./kits/flutter_ume_kit_ui/lib/components/touch_indicator/touch_indicator.dart.

The key steps are as follows:

1. The class of your plugin should implement PluggableWithNestedWidget.
2. Implements Widget buildNestedWidget(Widget child). Handling the nested widgets and returning the new Widget.

How to use UME in Release/Profile mode

Once you use flutter_ume in Release/Profile mode, you agree that you will bear the relevant risks by yourself.

The maintainer of flutter_ume does not assume any responsibility for the accident caused by this.

We recommend not to use it in Release/Profile mode for the following reasons:

1. VM Service is not available in these environments, so some functions are not available
2. In this environment, developers need to isolate the app distribution channels by themselves to avoid submitting relevant debugging code to the production environment

In order to use in Release/Profile mode, the details that need to be adjusted in the normal access process:

1. In pubspec.yaml, flutter_ume and plugins should be write below dependencies rather than dev_dependencies.
2. Don't put the code which call PluginManager.instance.register() and UMEWidget(child: App()) into conditionals which represent debug mode. (Such as kDebugMode)
3. Ensure the above details, run flutter clean and flutter pub get, then build your app.

About the third-party open-source project dependencies

• The TouchIndicator use the pub touch_indicator, the ColorPicker use the pub cyclop.
• We fork the package cyclop and modify some code meet our functional needs. We should depend cyclop by pub version after the PR being merged.
