Fixes https://github.com/flutter/flutter/issues/163430. This PR adds `engineId` field to `PlatformDispatcher`. When provided by the engine, this can be used to retrieve the engine instance from native code. Dart code: ```dart final identifier = PlatformDispatcher.instance.engineId!; ``` macOS, iOS: ```objc FlutterEngine *engine = [FlutterEngine engineForIdentifier: identifier]; ``` Android: ```java FlutterEngine engine = FlutterEngine.engineForId(identifier); ``` Linux ```cpp FlEngine *engine = fl_engine_for_id(identifier); ``` Windows ```cpp FlutterDesktopEngineRef engine = FlutterDesktopEngineForId(identifier); ``` *If you had to change anything in the [flutter/tests] repo, include a link to the migration guide as per the [breaking change policy].* ## Pre-launch Checklist - [X] I read the [Contributor Guide] and followed the process outlined there for submitting PRs. - [X] I read the [Tree Hygiene] wiki page, which explains my responsibilities. - [X] I read and followed the [Flutter Style Guide], including [Features we expect every widget to implement]. - [X] I signed the [CLA]. - [X] I listed at least one issue that this PR fixes in the description above. - [X] I updated/added relevant documentation (doc comments with `///`). - [X] I added new tests to check the change I am making, or this PR is [test-exempt]. - [X] I followed the [breaking change policy] and added [Data Driven Fixes] where supported. - [X] All existing and new tests are passing.
