Constructors
-
LocalizationsResolver.new({required Iterable<
Locale> supportedLocales, Locale? locale, LocaleListResolutionCallback? localeListResolutionCallback, LocaleResolutionCallback? localeResolutionCallback, Iterable<LocalizationsDelegate< ? localizationsDelegates})Object?> > -
Creates a LocalizationsResolver that determines the best-fit locale from the set of
supportedLocales
.
Properties
- hashCode → int
-
The hash code for this object.
no setterinherited
- hasListeners → bool
-
Whether any listeners are currently registered.
no setterinherited
- locale → Locale
-
The currently resolved Locale based on the current platform locale and
the provided set of supportedLocales.
no setter
- localeListResolutionCallback → LocaleListResolutionCallback?
-
This callback is responsible for choosing the app's locale
when the app is started, and when the user changes the
device's locale.
no setter
- localeResolutionCallback → LocaleResolutionCallback?
-
The signature of WidgetsApp.localeResolutionCallback.
no setter
-
localizationsDelegates
→ Iterable<
LocalizationsDelegate< Object?> > -
The delegates for this app's Localizations widget.
no setter
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
-
supportedLocales
→ Iterable<
Locale> -
The list of locales that this app has been localized for.

Methods
-
addListener(
VoidCallback listener) → void -
Register a closure to be called when the object changes.
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
-
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 -
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, such as
after a system back button press or back gesture.
inherited
-
didPushRoute(
String route) → Future< bool> -
Called when the host tells the application 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
-
dispose(
) → void -
Discards any resources used by the object. After this is called, the
object is not in a usable state and should be discarded (calls to
addListener will throw after the object is disposed).
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
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
notifyListeners(
) → void -
Call all the registered listeners.
inherited
-
removeListener(
VoidCallback listener) → void -
Remove a previously registered closure from the list of closures that are
notified when the object changes.
inherited
-
toString(
) → String -
A string representation of this object.
override
-
update(
{required Locale? locale, required LocaleListResolutionCallback? localeListResolutionCallback, required LocaleResolutionCallback? localeResolutionCallback, required Iterable< LocalizationsDelegate< ? localizationsDelegates, required Iterable<Object?> >Locale> supportedLocales}) → void - Replace one or more of the properties used for localization resolution and re-resolve the locale.
Operators
-
operator ==(
Object other) → bool -
The equality operator.
