[Poloten]

Please help me. How to get context to localize notification in Application, if app - terminated

I try "GlobalKey" but navigatorKey.currentContext - always null;

final GlobalKey<NavigatorState> navigatorKey = GlobalKey<NavigatorState>();

@pragma('vm:entry-point')
Future<void> _firebaseMessagingBackgroundHandler(RemoteMessage message) async {
  if (!hasBeenInitializedFireBase) {
    await Firebase.initializeApp(options: DefaultFirebaseOptions.currentPlatform);

    hasBeenInitializedFireBase = true;
  }
  await setupFlutterNotifications();
  showFlutterNotification(message);
}

showFlutterNotification(RemoteMessage message) {
// How to get context here to localize string like a S.of(context).noData
}


FirebaseMessaging.onBackgroundMessage(_firebaseMessagingBackgroundHandler);
