Method Detail

configureFlutterEngine

void configureFlutterEngine(@NonNull
                            FlutterEngine flutterEngine)

Configures the given FlutterEngine.

This method is called after the given FlutterEngine has been attached to the owning FragmentActivity. See ActivityControlSurface.attachToActivity( ExclusiveAppComponent, Lifecycle).

It is possible that the owning FragmentActivity opted not to connect itself as an ActivityControlSurface. In that case, any configuration, e.g., plugins, must not expect or depend upon an available Activity at the time that this method is invoked.

cleanUpFlutterEngine

void cleanUpFlutterEngine(@NonNull
                          FlutterEngine flutterEngine)

Cleans up references that were established in configureFlutterEngine(FlutterEngine) before the host is destroyed or detached.
