how capture click in notification with app closed to redirect a specific page in firebase messaging > 9.0

I am using version 9.0 of firebase messaging and wishing the user to a specific screen when receiving and clicking on a notification when the app is closed.

I can currently manage with the app open or minimized, but I don't understand how to perform this action when the app is not open.

Future<void> _firebaseMessagingBackgroundHandler(RemoteMessage message) async {

  await Firebase.initializeApp();
  Model model = Model();
  id = "sasassa;
  Get.offNamed("$SCREEN_ROUTE",arguments: model);
  Storage storage = Storage();
  storage.setReceivedNotification(true);
  print("teste notificação recebida");

}

FirebaseMessaging.instance.getInitialMessage().then((message){
    if (message != null){
      Model model = Model();
      id = "sasassa;
      Get.offNamed("$SCREEN_ROUTE",arguments: model);
    }
  });

  FirebaseMessaging.onMessageOpenedApp.listen((RemoteMessage message) {
    print("a");
    storage.setReceivedNotification(true);
    Model model = Model();
    id = "sasassa;
    Get.offNamed("$SCREEN_ROUTE",arguments: model);
    //Navigator.pushNamed(context, '/events');
  });


  FirebaseMessaging.onMessage.listen((RemoteMessage message) async {
    print("b");
    storage.setReceivedNotification(true);
    print("teste b $message");
    String? corpo = message.notification?.body;
    String? titulo = message.notification?.title;
    String? image = message.notification?.android?.imageUrl;
    //showMyDialog(titulo: titulo,corpo: corpo);

    print("$corpo $titulo $image");

  });

I tried to use shared preference in backgroundHandler, but this way the redirect will happen even without the user clicking on the notification.

Would anyone have instructions on how to redirect a with the app closed from the click on a specific notification?

PS: I know I need to send the data in the notification body, I just want to understand how to make the flutter capture the click with the app closed in version 9.0 or higher.

Use FirebaseMessaging.instance.getInitialMessage() method to get messages

If App is Closed/Killed

  FirebaseMessaging.instance
          .getInitialMessage()
          .then((RemoteMessage message) {
      print("FirebaseMessaging.getInitialMessage $message");
   });

Use FirebaseMessaging.onMessageOpenedApp method to get messages

If App is in background

   FirebaseMessaging.onMessageOpenedApp
            .listen((RemoteMessage message) {
      print("FirebaseMessaging.onMessageOpenedApp $message");
   });

Use FirebaseMessaging.onMessage method will receive a message

If App is in foreground

   FirebaseMessaging.onMessage
         .listen((RemoteMessage message) {
      print("FirebaseMessaging.onMessage $message");
   });
