FlutterActivityDelegate

public interface FlutterActivityEvents
extends ComponentCallbacks2, PluginRegistry.ActivityResultListener, PluginRegistry.RequestPermissionsResultListener

A collection of Android Activity methods that are relevant to the core operation of Flutter applications.

Application authors that use an activity other than FlutterActivity should forward all events herein from their activity to an instance of FlutterActivityDelegate in order to wire the activity up to the Flutter framework. This forwarding is already provided in FlutterActivity.
