PushTokenRefresher class

Keeps the backend's push-token record in sync with FCM's silently-rotating token. The host calls registerPushToken once on initial registration; this service then takes over and re-uploads the current token whenever it has changed (rotation) or whenever the last successful upload is older than _refreshInterval (drift insurance).

Triggers:

  • Cold start (called immediately on initialize)
  • App foreground (AppLifecycleState.resumed) — closes the background-to-foreground gap that the host's own initState pattern misses, which is the most common cause of "registration-token-not- registered" on iOS.
  • FCM rotates the token mid-session (FirebaseMessaging.onTokenRefresh)
Mixed-in types

A representation of the runtime type of the object.

Methods

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.
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.
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, 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
Synchronous teardown. The observer and client reference are cleared immediately so any in-flight lifecycle/onTokenRefresh callback that races against shutdown short-circuits at the _client == null guard. The stream subscription is cancelled in the background — its future is intentionally not awaited because callers of RelevaClient.dispose are synchronous.
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
handleStatusBarTap() → void
Called when the user taps the status bar on iOS, to scroll a scroll view to the top.
inherited
handleUpdateBackGestureProgress(PredictiveBackEvent backEvent) → void
Called when a predictive back gesture moves.
inherited
initialize(RelevaClient client) → Future<void>
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
refresh(RelevaClient client) → Future<void>
Manually trigger a refresh. Fetches the current FCM token and re-uploads if it has changed since the last successful upload, or if the last upload is older than _refreshInterval.
toString() → String
A string representation of this object.
