Methods
-
build(
BuildContext context) → void -
Called everytime the HookState is requested.
override
-
deactivate(
) → void -
Equivalent of State.deactivate for HookState.
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.
override
-
didChangeAppLifecycleState(
AppLifecycleState state) → void -
Called when the system puts the app in the background or returns
the app to the foreground.
override
-
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.
override

didChangeMetrics(
) → void -

when a phone is rotated.
override
-
didChangePlatformBrightness(
) → void -
Called when the platform brightness changes.
override
-
didChangeTextScaleFactor(
) → void -
Called when the platform's text scale factor changes.
override
-
didChangeViewFocus(
ViewFocusEvent event) → void -
Called whenever the PlatformDispatcher receives a notification that the
focus state on a view has changed.
override
-
didHaveMemoryPressure(
) → void -
Called when the system is running low on memory.
override
-
didPopRoute(
) → Future< bool> -
Called when the system tells the app to pop the current route, such as
after a system back button press or back gesture.
override
-
didPushRoute(
String route) → Future< bool> -
Called when the host tells the application to push a new route onto the
navigator.
override
-
didPushRouteInformation(
RouteInformation routeInformation) → Future< bool> -
Called when the host tells the application to push a new
RouteInformation and a restoration state onto the router.
override
-
didRequestAppExit(
) → Future< AppExitResponse> -
Called when a request is received from the system to exit the application.
override
-
didUpdateHook(
LifecycleHook oldHook) → void -
Equivalent of State.didUpdateWidget for HookState.
inherited
-
dispose(
) → void -
Equivalent of State.dispose for HookState.
override
-
handleCancelBackGesture(
) → void -
Called when a predictive back gesture is canceled, indicating that no
navigation should occur.
override
-
handleCommitBackGesture(
) → void -
Called when a predictive back gesture is finished successfully, indicating
that the current route should be popped.
override
-
handleStartBackGesture(
PredictiveBackEvent backEvent) → bool -
Called at the start of a predictive back gesture.
override
-
handleUpdateBackGestureProgress(
PredictiveBackEvent backEvent) → void -
Called when a predictive back gesture moves.
override
-
initHook(
) → void -
Equivalent of State.initState for HookState.
override
-
markMayNeedRebuild(
) → void -
Mark the associated HookWidget as potentially needing to rebuild.
inherited
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
onDetached(
) → void -
reassemble(
) → void -
In addition to this method being invoked, it is guaranteed that the
build method will be invoked when a reassemble is signaled. Most
widgets therefore do not need to do anything in the reassemble method.
inherited
-
setState(
VoidCallback fn) → void -
Equivalent of State.setState for HookState.
inherited
-
shouldRebuild(
) → bool -
Called before a build triggered by markMayNeedRebuild.
inherited
-
toDiagnosticsNode(
{String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode -
Returns a debug representation of the object that is used by debugging
tools and by DiagnosticsNode.toStringDeep.
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.
inherited
Operators
