activate(
) → void - Called when this object is reinserted into the tree after having been removed via deactivate.
-
deactivate(

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.
-
didChangeAccessibilityFeatures(
) → void - Called when the system changes the set of active accessibility features.
-
didChangeAppLifecycleState(
AppLifecycleState state) → void - Called when the system puts the app in the background or returns the app to the foreground.
-
didChangeDependencies(
) → void - Called when immediately after initState. Otherwise called only if a dependency of an InheritedWidget.
-
didChangeLocales(
List< Locale> ? locales) → void - Called when the system tells the app that the user's locale has changed.
-
didChangeMetrics(
) → void - Called when the application's dimensions change. For example, when a phone is rotated.

override
-
didPopNext(
) → void -
The top route has been popped off, and this route shows up.
override
-
didPopRoute(

didPush(
) → void -
Called when this route has been pushed.
override
-
didPushNext(
) → void -
New route has been pushed, and this route is no longer visible.
override
-
didPushRoute(
String route) → Future< bool> - Called when the host tells the app to push a new route onto the navigator.
-
didPushRouteInformation(
RouteInformation routeInformation) → Future< bool> - Called when the host tells the application to push a new RouteInformation and a restoration state onto the router.
-
didUpdateWidget(
StatefulWidget oldWidget) → void - Override this method to respond when the StatefulWidget is recreated.
-
dispose(
) → void -
The framework calls this method when this
StateXobject will never build again. Note: YOU WILL HAVE NO IDEA WHEN THIS WILL RUN in the Framework. -
inactiveLifecycleState(
) → void - The application is in an inactive state and is not receiving user input.
-
initState(
) → void -
The framework will call this method exactly once.
Only when the
StateXobject is first created. -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
pausedLifecycleState(
) → void - The application is not currently visible to the user, not responding to user input, and running in the background.
-
reassemble(
) → void - Called whenever the application is reassembled during debugging, for example during hot reload.
-
resumedLifecycleState(
) → void - The application is visible and responding to user input.
-
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.
