StateXController class

Your 'working' class most concerned with the app's functionality. Add it to a 'StateX' object to associate it with that State object.

Mixed-in types
Implementers

Constructors

StateXController([StateX<StatefulWidget>? state])
Optionally supply a State object to 'link' to this object. Thus, assigned as 'current' StateX for this object

Properties

dataObject ↔ Object?
This is of type Object allowing you to propagate any class object you wish down the widget tree.
getter/setter pairinherited
hashCode → int
The hash code for this object.
no setterinherited
identifier → String
A unique key is assigned to all State Controllers, State objects, and listeners. Used in large projects to separate objects into teams.
no setterinherited
inDebugger → bool
Deprecated soon. Use inDebugMode.
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
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
state → StateX<StatefulWidget>?
The current StateX object.
no setter
states → Set<StateX<StatefulWidget>>
Return a 'copy' of the Set of State objects.
no setterinherited

Methods

activate() → void
Called when this object is reinserted into the tree after having been removed via deactivate.
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.
afterListener(String key) → StateListener?
Retrieve the 'after' listener by its unique key.
beforeListener(String key) → StateListener?
Retrieve the 'before' listener by its unique key.
buildInherited() → void
Rebuild the InheritedWidget of the 'closes' InheritedStateX object if any.
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 a InheritedWidget
detachedLifecycleState() → 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
Called when the system changes the set of 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 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 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 route has been popped off.
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 route has been pushed.
inherited
didPushNext() → void
New route has been pushed, and this route is no longer visible.
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
didUpdateWidget(StatefulWidget oldWidget) → void
Override this method to respond when the StatefulWidget is recreated.
inherited
dispose() → void
The framework calls this method when this StateX object will never build again. Note: YOU WILL HAVE NO IDEA WHEN THIS WILL RUN in the Framework.
inherited
inactiveLifecycleState() → void
The application is in an inactive state and is not receiving user input.
inherited
initAsync() → Future<bool>
Used to complete asynchronous operations
inherited
initState() → void
The framework will call this method exactly once. Only when the StateX object is first created.
inherited
listControllers(List<String> keys) → List<StateXController?>
Return a List of Controllers specified by key id.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyClients() → void
In harmony with Flutter's own API Rebuild the InheritedWidget of the 'closes' InheritedStateX object if any.
ofState<T extends StateX<StatefulWidget>>() → T?
Retrieve the StateX object by type Returns null if not found
inherited
onAsyncError(FlutterErrorDetails details) → void
Supply an 'error handler' routine if something goes wrong in the corresponding initAsync() routine.
inherited
pausedLifecycleState() → 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
resumedLifecycleState() → void
The application is visible and responding to user input.
inherited
setRootStateX(StateX<StatefulWidget> state) → void
Important to record the 'root' StateX object. Its InheritedWidget!
inherited
setState(VoidCallback fn) → void
Provide the setState() function to external actors
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.
inherited
updateNewStateX(covariant StateX<StatefulWidget> oldState) → void
A State object may be unexpectedly re-created by a UniqueKey() in a parent for example. You have to 'update' the properties of the new StateX object using the old StateX object because it's going to be disposed of.

The equality operator.
