The old Android platform-side wrappers hosting the Flutter runtime at io.flutter.app.FlutterActivity and their associated classes are now deprecated. New wrappers at io.flutter.embedding.android.FlutterActivity and associated classes now replace them. Those classes better support real world scenarios where the FlutterActivity isn't the first and only Android Activity in an application.
