Happy new year!

Shared Elements API!

After a lot of iteration and work, this release adds support for Compose's new shared elements APIs.

These are still experimental and subject to change, both in Circuit and due to how the underlying

See this PR for full details as well as sample integrations: https://github.com/slackhq/circuit/pull/1550. Please share feedback in this discussion. More formal docs to come as well, we'll publish updates there!

For now, the easiest way to support shared element transitions is to wrap your content with a SharedElementTransitionLayout.

CircuitCompositionLocals(circuit) {
  SharedElementTransitionLayout {
    NavigableCircuitContent(
      navigator = navigator,
      backStack = backStack,
    )
  }
}

SharedElementTransitionLayout creates and provides a SharedElementTransitionScope to content within it, and in turn exposes a SharedTransitionScope for use with standard compose shared elements/bounds animations. This is supported in NavigableCircuitContent and overlays.

There is also a PreviewSharedElementTransitionLayout for help with Compose previews.

Behaviour Changes: rememberRetained

Previously, rememberRetained could sometimes restore values when a composable was re-added, depending on whether its parent RetainedStateRegistry had been saved (#​1783).
Now, rememberRetained aligns with remember and rememberSaveable: if a composable is removed and later re-added, its value will not be restored unless it is explicitly saved and then restored via the registry.

Update rememberRetained to allow CanRetainChecker to be updated in place.

Behaviour Change: RetainedStateRegistry

• saveAll now returns the saved values.
• RetainedStateRegistry.Entry.unregister now returns whether the unsaved valueProvider was actually removed.
• saveAll and saveValue now skip storing child values when CanRetainChecker returns false.

New: RetainedStateHolder

Similar to SaveableStateHolder, RetainedStateHolder provides a mechanism to maintain separate RetainedStateRegistry entries for specific keys. This allows saving the state defined with rememberRetained for a subtree before it is disposed, so that the subtree can later be recomposed with its state restored.

val retainedStateHolder = rememberRetainedStateHolder()
var currentTab by remember { mutableStateOf(TabA) }

retainedStateHolder.RetainedStateProvider(key = currentTab.name) {
  // rememberRetained values in tab content are preserved across tab switches
  when (currentTab) {
    TabA -> {
      TabAContent()
    }
    TabB -> {
      TabBContent()
    }
    TabC -> {
      TabCContent()
    }
  }
}

Implementation Changes: NavigableCircuitContent

• The approach of managing a separate RetainedStateRegistry for each record has been changed to use RetainedStateHolder instead.
• Change SaveableStateHolder to release saved states of removed records.
