Methods

build() → FutureOr<AppLifecycleState>
Initialize an AsyncNotifier.
didChangeAccessibilityFeatures() → void
Called when the system changes the set of currently active accessibility features.
inherited
didChangeAppLifecycleState(AppLifecycleState state) → void
Called when the system puts the app in the background or returns the app to the foreground.
override
didChangeLocales(List<Locale>? locales) → void
Called when the system tells the app that the user's locale has changed. For example, if the user changes the system language settings.
inherited
didChangeMetrics() → void
Called when the application's dimensions change. For example, when a phone is rotated.
inherited
didChangePlatformBrightness() → void
Called when the platform brightness changes.
inherited
didChangeTextScaleFactor() → void
Called when the platform's text scale factor changes.
inherited
didChangeViewFocus(ViewFocusEvent event) → void
Called whenever the PlatformDispatcher receives a notification that the focus state on a view has changed.
inherited
didHaveMemoryPressure() → void
Called when the system is running low on memory.
inherited
didPopRoute() → Future<bool>
Called when the system tells the app to pop the current route, such as after a system back button press or back gesture.
inherited
didPushRoute(String route) → Future<bool>
Called when the host tells the application to push a new route onto the navigator.
inherited
didPushRouteInformation(RouteInformation routeInformation) → Future<bool>
Called when the host tells the application to push a new RouteInformation and a restoration state onto the router.
inherited
didRequestAppExit() → Future<AppExitResponse>
Called when a request is received from the system to exit the application.
inherited
handleCancelBackGesture() → void
Called when a predictive back gesture is canceled, indicating that no navigation should occur.
inherited
handleCommitBackGesture() → void
Called when a predictive back gesture is finished successfully, indicating that the current route should be popped.
inherited
handleStartBackGesture(PredictiveBackEvent backEvent) → bool
Called at the start of a predictive back gesture.
inherited
handleUpdateBackGestureProgress(PredictiveBackEvent backEvent) → void
Called when a predictive back gesture moves.
inherited
listenSelf(void listener(AsyncValue<AppLifecycleState>? previous, AsyncValue<AppLifecycleState> next), {void onError(Object error, StackTrace stackTrace)?}) → RemoveListener
Listens to changes on the value exposed by this provider.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
runBuild() → void
Executes Notifier.build.
inherited
toString() → String
A string representation of this object.
inherited
update(FutureOr<AppLifecycleState> cb(AppLifecycleState previousState), {FutureOr<AppLifecycleState> onError(Object err, StackTrace stackTrace)?}) → Future<AppLifecycleState>
A function to update state from its previous value, while abstracting loading/error cases for state.
inherited
updateShouldNotify(AsyncValue<AppLifecycleState> previous, AsyncValue<AppLifecycleState> next) → bool
A method invoked when the state exposed by this Notifier changes. It compares the previous and new value, and return whether listeners should be notified.
