dataObject Object?
This is of type Object allowing you to propagate any class object you wish down the widget tree.

didCallChangeEvent bool
The 'Change' event has already been called in a previous State object
no setterinherited
firstState → StateX<StatefulWidget>?
Return the first State object
no setterinherited

Whether any listeners are currently registered.
no setterinherited
hasChangeNotifierImpl bool
A flag. Instantiated Change Notifier
no setterinherited
hashCode int
The hash code for this object.
no setterinherited
identifier String
A unique key is assigned to all State Controllers, State objects Used in large projects to separate objects into teams.
no setterinherited
inDebugMode bool
Determines if running in an IDE or in production. Returns true if the App is under in the Debugger and not production.
no setterinherited
lastContext BuildContext?
Returns the 'latest' context in the App.
no setterinherited
lastState → StateX<StatefulWidget>?
Return the 'latest' State object
no setterinherited
rootState → AppStateX<StatefulWidget>?
Returns the 'first' StateX object in the App
no setterinherited
runtimeType Type
A representation of the runtime type of the object.
no setterinherited
setBuilderUsed bool
A flag. Noting if the function above is ever used.
no setterinherited
state → StateX<StatefulWidget>?

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
didChangeMetrics() → void
Called when the application's UI dimensions change. For example, when a phone is rotated.
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.
inherited
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
onConnectivityChanged(ConnectivityResult result) → void
If the device's connectivity changes.
inherited
pausedAppLifecycleState() → void
The application is not currently visible to the user, not responding to user input, and running in the background.
inherited
reassemble() → void
Called whenever the application is reassembled during debugging, for example during hot reload.
inherited
removeListener(VoidCallback listener) bool
Remove a previously registered closure from the list of closures that are notified when the object changes.
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.
