Methods

activate() → void

addAfterListener(StateListener listener) bool
Add a listener fired 'after' the main controller runs.
inherited
addBeforeListener(StateListener listener) bool
Add a listener fired 'before' the main controller runs.
inherited
addConId(ControllerMVC con) String
Adds a 'Controller' to be associated with this StateMVC object and returns Controller's the unique 'key' identifier assigned to it.
inherited
addList(List<ControllerMVC>? list) → void
Add a list of 'Controllers' to be associated with this StatMVC object.
inherited
addListener(StateListener listener) bool
Add a listener fired 'after' the main controller runs.
inherited
afterContains(StateListener listener) bool
Returns true of the listener specified is already added.
inherited
afterList(List<String> keys) List<StateListener>
inherited
afterListener(String key) StateListener?
Returns the specified 'after' listener.
inherited
beforeContains(StateListener listener) bool
Returns true of the listener specified is already added.
inherited
beforeList(List<String> keys) List<StateListener>
inherited
beforeListener(String key) StateListener?
Returns the specified 'before' listener.
inherited
build(BuildContext context) Widget
Provide 'the view'
override
buildApp(BuildContext context) Widget
Implement this function to compose the App's View. Override to impose your own WidgetsApp (like CupertinoApp or MaterialApp)
inherited
catchError(Exception? ex) → void
Catch and explicitly handle the error.
inherited
contains(ControllerMVC con) bool
Returns true if the specified 'Controller' is associated with this StateMVC object.
inherited
controllerById(String keyId) → ControllerMVC?
Retrieve a Controller by its a unique String identifier.
inherited
controllerByType<U extends ControllerMVC?>() → U?
Retrieve a Controller in the widget tree by type. Retrieve a Controller in the MVC framework by type.
inherited
deactivate() → void
The framework calls this method whenever it removes this State object from the tree.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node.
inherited
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.
inherited
didChangeDependencies() → void
Called when a dependency of this State object changes. This method is also called immediately after initState.
inherited
didChangeLocale(Locale locale) → 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
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. For example, on Android, this is called when the user presses the back button. Observers are notified in registration order until one returns true. If none return true, the application quits.
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.
inherited
didUpdateWidget(covariant StatefulWidget oldWidget) → void
Override this method to respond when the widget changes (e.g., to start implicit animations).
inherited
dispose() → void
The framework calls this method when this StateMVC object will never build again.
override
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
initAsync() Future<bool>
Initialize any 'time-consuming' operations at the beginning. Initialize asynchronous items essential to the Mobile Applications. Typically called within a FutureBuilder() widget.
inherited
initState() → void
The framework will call this method exactly once. Only when the StateMVC object is first created.
inherited
listControllers(List<String> keys) List<ControllerMVC?>
Returns the list of 'Controllers' associated with this StateMVC object.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
onAsyncError(FlutterErrorDetails details) bool
Supply an 'error handler' routine if something goes wrong in the corresponding initAsync() routine.
inherited
onError(FlutterErrorDetails details) → void
Supply an 'error handler' routine to fire when an error occurs. Allows the user to define their own with each Controller.
inherited
reassemble() → void
During development, if a hot reload occurs, the reassemble method is called. This provides an opportunity to reinitialize any data that was prepared in the initState method.
inherited
refresh() → void
Calls the State object's refresh() function if not already in the SetState.builder() function (see class SetState below). The refresh() function is just another name used to call the State object's setState() function.
inherited
remove(String keyId) bool
Remove a specific associated 'Controller' from this StateMVC object by using its unique 'key' identifier.
inherited
removeListener(StateListener listener) bool
Removes the specified listener.
inherited
setState(VoidCallback fn) → void

inherited
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) String
A string representation of this object.
inherited
toStringShort() String
A brief description of this object, usually just the runtimeType and the hashCode.
