Fixes https://github.com/flutter/flutter/issues/173554
This PR forwards scene lifecycle events from the SceneDelegate to
registered plugins.
This PR introduced 3 new public APIs:
* `FlutterSceneLifeCycleDelegate` (protocol) - This is the protocol that
plugins conform to
* `FlutterSceneLifeCycleProvider` (protocol) - This is the protocol that
a SceneDelegate can conform to instead of `FlutterSceneDelegate`
* `FlutterPluginSceneLifeCycleDelegate` (interface) - This is the class
object that a SceneDelegate using `FlutterSceneLifeCycleProvider` can
use to forward scene events to
The flow of events are as followed when SceneDelegate subclasses the
`FlutterSceneDelegate`:
* `FlutterSceneDelegate` receives `sceneDidBecomeActive` event from
UIKit
* `FlutterSceneDelegate` forwards `sceneDidBecomeActive` to
`FlutterPluginSceneLifeCycleDelegate`
* `FlutterPluginSceneLifeCycleDelegate` loops through each
`FlutterEngine` it has and forwards `sceneDidBecomeActive` to the
engine's `FlutterEnginePluginSceneLifeCycleDelegate`
* `FlutterEnginePluginSceneLifeCycleDelegate` loops through each plugin
that conforms to `FlutterSceneLifeCycleDelegate` it has and forwards
`sceneDidBecomeActive` to the plugin
* `FlutterPluginSceneLifeCycleDelegate` forwards `sceneDidBecomeActive`
to `FlutterPluginAppLifeCycleDelegate` using
`sceneDidBecomeActiveFallback`
* `FlutterPluginAppLifeCycleDelegate` loops through all plugins and
calls `applicationDidBecomeActive` if the plugin does not conform to
`FlutterSceneLifeCycleDelegate`
When using `FlutterSceneLifeCycleProvider` instead of
`FlutterSceneDelegate`, scene events are manually forwarded to
`FlutterPluginSceneLifeCycleDelegate` by the iOS developer. For example:
```swift
class SceneDelegate: UIResponder, UIWindowSceneDelegate, FlutterSceneLifeCycleProvider {
var sceneLifeCycleDelegate: FlutterPluginSceneLifeCycleDelegate = FlutterPluginSceneLifeCycleDelegate()
func sceneDidBecomeActive(_ scene: UIScene) {
sceneLifeCycleDelegate.sceneDidBecomeActive(scene)
}
```

This change adds support for two DTD Editor service RPCs and makes
functionality that's dependent on the availability of the Editor service
reactive to the service availability changing.
The newly added `getActiveLocation` Editor RPC now allows for us to
properly determine which source file is selected at startup, removing
the need for special casing around initializing the filtered preview
set.
The `navigateToCode` Editor RPC is now supported, and URIs in stack
traces can now be clicked to navigate to the source location in the IDE.
Both filtering previews by selected file and stack frame navigation
links are only enabled when the Editor service is available.
Fixes https://github.com/flutter/flutter/issues/176113
Taken partially from https://github.com/flutter/flutter/pull/170446 with
only the changes to add a ScaleTranslate rectangle transform method
brought over. Unlike the original PR, this PR will apply that optimized
method for any caller who transforms a rectangle rather than just the
matrix/clip tracker for the engine layer tree code.
A benchmark for the new methods is also provided to verify their
improved performance.
Closes https://github.com/flutter/flutter/issues/92040
- Adds `expanded` semantics flag support to Android
- Adds `onExpand` and `onCollapse` semantics actions
- Updates `robolectric` library
- Adds java and dart tests
#### Why were `onExpand` and `onCollapse` actions added?
It turned out that TalkBack doesn't announce the `expanded` state if
`expand/collapse` action is not set for the accessibility node.
#### Why was the `robolectric` library updated?
The `expanded` state support in Android was introduced in API 36. The
`roboelectric: 4.14.1` doesn't support API 36. To run tests for a newly
added functionality `roboelectric` library was updated to `4.16`, which
supports the latest Android version
(https://github.com/robolectric/robolectric/releases/tag/robolectric-4.16).
In case you think it would be better to update the `roboelectric` in a
separate PR, please let me know.

## What's new?
- Implement and test `_window_win32.dart`, the Win32 implementation of
`_window.dart` 🎉
- Wrote a bunch of tests in `window_win32_test.dart` which uses a mock
API barrier to mock the native Win32 layer
- Update `BaseWindowController` to extend `ChangeNotifier` and use it to
inform the `WindowScope` of when things change
- Made `RegularWindowController.empty()` a non-internal constructor, as
it is needed by implementations
- Added a _large_ example application for windowing where users can test
out different windowing concepts and see how they work!
To test, simply run the tests or try out the example app!
