Method Documentation

addFlutterManagedEngine:

- (BOOL) addFlutterManagedEngine:

(FlutterEngine *)

engine

Associates the FlutterEngine with the FlutterPluginSceneLifeCycleDelegate so that it will forward scene events to the plugins within the engine.

Returns NO if the engine is already associated with the delegate.

engine:receivedConnectNotificationFor:

- (void) engine:		(FlutterEngine *)	engine
receivedConnectNotificationFor:		(UIScene *)	scene

fromScene:

+ (FlutterPluginSceneLifeCycleDelegate *) fromScene:

(UIScene *)

scene

removeFlutterManagedEngine:

- (BOOL) removeFlutterManagedEngine:

(FlutterEngine *)

engine

Removes the FlutterEngine from the FlutterPluginSceneLifeCycleDelegate so that it will no longer forward scene events to the plugins within the engine.

Returns NO if the engine is not associated with the delegate.

scene:restoreInteractionStateWithUserActivity:

- (void) scene:		(UIScene *)	scene
restoreInteractionStateWithUserActivity:		(NSUserActivity *)	stateRestorationActivity

stateRestorationActivityForScene:

- (NSUserActivity *) stateRestorationActivityForScene:

(UIScene *)

scene

developerManagedEngines

- (NSPointerArray*) developerManagedEngines

readwritenonatomicstrong

An array of weak pointers to FlutterEngines that have views within this scene. Developers manually add engines to this array.

It is up to the developer to keep this list up-to-date.

flutterManagedEngines

- (NSPointerArray*) flutterManagedEngines

readwritenonatomicstrong

An array of weak pointers to FlutterEngines that have views within this scene. Flutter automatically adds engines to this array.

This array is lazily cleaned up. updateFlutterManagedEnginesInScene: should be called before use to ensure it is up-to-date.
