Methods

activate() → void
Called when this object is reinserted into the tree after having been removed via deactivate.
inherited
addListener(VoidCallback listener) → bool
Register a closure to be called when the object changes.
inherited
addState(StateX<StatefulWidget>? state) → String
Associate this StateXController to the specified State object to use that State object's functions and features. Returns that State object's unique identifier.
inherited
deactivate() → void
The framework calls this method whenever it removes this StateX object from the tree.
inherited
dependOnInheritedWidget(BuildContext? context) → bool
Link a widget to an InheritedWidget
inherited
detachedAppLifecycleState() → void
Either be in the progress of attaching when the engine is first initializing or after the view being destroyed due to a Navigator pop.
inherited
didChangeAccessibilityFeatures() → void
Either be in the progress of attaching when the engine is first initializing or after the view being destroyed due to a Navigator pop.
inherited
didChangeAppLifecycleState(AppLifecycleState state) → void
Called when the system puts the app in the background or returns the app to the foreground.
inherited
didChangeDependencies() → void
Called when immediately after initState. Otherwise called only if a dependency of an InheritedWidget.
inherited
didChangeLocales(List<Locale>? locales) → void
Called when the system tells the app that the user's locale has changed.

inherited
didChangePlatformBrightness() → void
Brightness changed.
inherited
didChangeTextScaleFactor() → void
Called when the platform's text scale factor changes.
inherited
didHaveMemoryPressure() → void
Called when the system is running low on memory.
inherited
didPop() → void
Called when this State is popped off a route.
inherited
didPopNext() → void
The top route has been popped off, and this route shows up.
inherited
didPopRoute() → Future<bool>
Called when the system tells the app to pop the current route. For example, on Android, this is called when the user presses the back button.
inherited
didPush() → void
Called when this State is first added to as a Route observer?!
inherited
didPushNext() → void
New route has been pushed, and this State object's route is no longer current.
inherited
didPushRoute(String route) → Future<bool>
Called when the host tells the app 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. Exiting the application can proceed with AppExitResponse.exit; Cancel and do not exit the application with AppExitResponse.cancel;
inherited
didUpdateWidget(covariant StatefulWidget oldWidget) → void
Override this method to respond to when the StatefulWidget is recreated.
inherited
dispose() → void
Part of the Flutter engine's 'garbage collection' process. Note: YOU WILL HAVE NO IDEA WHEN THIS WILL RUN in the Framework. BEST NOT TO USE THIS FUNCTION EVER!
inherited
disposeChangeNotifier() → void
Don't forget to call this method in the appropriate dispose() function!
inherited
forEachState(void func(StateX<StatefulWidget> state), {bool? reversed}) → bool
To externally 'process' through the State objects. Invokes func on each StateX possessed by this object.
inherited
hiddenAppLifecycleState() → void
All views of an application are hidden, either because the application is about to be paused (on iOS and Android), or because it has been minimized or placed on a desktop that is no longer visible (on non-web desktop), or is running in a window or tab that is no longer visible (on the web).
inherited
inactiveAppLifecycleState() → void
The application is in an inactive state and is not receiving user input.
inherited
initAsync() → Future<bool>
Initialize any 'time-consuming' operations at the beginning. Implement any asynchronous operations needed done at start up.
inherited
initChangeNotifier() → void
inherited
initState() → void
The framework will call this method exactly once. Only when the StateX object is first created.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyClients() → bool
In harmony with Flutter's own API Rebuild the InheritedWidget of the 'closes' InheritedStateX object if any.
inherited
notifyListeners() → bool
Call all the registered listeners.
inherited
ofState<T extends StateX<StatefulWidget>>() → T?
Retrieve the StateX object of type T Returns null if not found
inherited
onAsyncError(FlutterErrorDetails details) → void
initAsync() has failed and a 'error' widget instead will be displayed. This takes in the snapshot.error details.
inherited
onChanged(T? v) → void
Called when a button is changed.
pausedAppLifecycleState() → void
The application is not currently visible to the user, not responding to user input, and running in the background.
inherited
reassemble() → void

inherited
removeListener(VoidCallback listener) → bool

inherited
resumedAppLifecycleState() → void
The application is visible and responding to user input.
inherited
setBuilder(MaybeBuildWidgetType? builder) → Widget
Returns a widget from builder assuming the current object is a Listenable const SizedBox.shrink() otherwise
inherited
setRootStateX(StateX<StatefulWidget>? state) → bool
Important to record the 'root' StateX object. Its an InheritedWidget!
inherited
setState(VoidCallback fn) → void
Call a State object's setState() and notify any listeners
inherited
stateOf<T extends StatefulWidget>() → StateX<StatefulWidget>?
Retrieve the State object by its StatefulWidget. Returns null if not found.
inherited
toString() → String
A string representation of this object.
