🐛 [firebase_messaging] getInitialMessage returning incorrect data

[keithcwk]

Bug report

Describe the bug
When the app is launched from a cold start scenario, getInitialMessage is called, however, the value of initialMessage is null in majority of the cases

In my application, getInitialMessage is used to provide a path to redirect to, located in initialMessage.data. However, when logging the value of initialMessage.data, there are multiple instances where it is logged as null

This causes the redirect from push notification feature to be quite unusable, and our app is facing this issue on production.

Steps to reproduce

Steps to reproduce the behavior:

1. Ensure that await FirebaseMessaging.instance.getInitialMessage is in the initState of main.dart
2. Add print statement to print the contents of getInitialMessage
3. Send a notification to the device with data
4. Click on the notification

Expected behavior

The value of initialMessage returns data of initialMessage that was recently consumed

Sample project

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(
    options: DefaultFirebaseOptions.currentPlatform,
  );

  runApp(
    const ProviderScope(
      child: MyApp(),
    ),
  );
}

class MyApp extends ConsumerStatefulWidget {
  const MyApp({
    super.key,
  });
  @override
  MyAppState createState() => MyAppState();
}

class MyAppState extends ConsumerState<MyApp> {
  Future<void> handleNotificationData() async {
    RemoteMessage? initialMessage =
        await FirebaseMessaging.instance.getInitialMessage();

    Logger.logFuncValues(LoggerKeys.handleNotifData, initialMessage?.data);

    if (initialMessage?.data['path'] != null) {
      Logger.logFuncStart(LoggerKeys.onInitialMessage);
      redirect(initialMessage?.data['path']);
    }

    FirebaseMessaging.onMessageOpenedApp.listen(
      (RemoteMessage message) async {
        Logger.logFuncValues(LoggerKeys.onMessageOpenedApp, message.data);

        redirect(message.data['path']);
      },
    );
  }

  @override
  void initState() {
    handleNotificationData();

    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return const Directionality(
      textDirection: TextDirection.ltr,
      child: Scaffold(
        body: Center(child: Text('test')),
      ),
    );
  }
}

@keithcwk does this occur on Android or iOS? On my side Android redelivers the same notification multiple times whereas on iOS, once the notification is consumed it does not get delivered again.

[keithcwk]

@bqubique it occurs on both Android and iOS

[Lyokone]

Hello @keithcwk, are you testing this in release mode instead of debug? Notification will sometime not be properly passed through when using debug mode.

[keithcwk]

@Lyokone As i've mentioned, this is a production issue, and we do have genuine complaints from our users. All the instances of the errors are all coming from release mode & production as well

[matt-hall-zory]

Same issue here. Running from release mode, force closing and booting from terminated state, it appears to be that the issue is intermittent failure of the entire system. Force closing and booting my app and about 50% of the time I can't even retrieve fcmToken.
When installing and booting directly from flutter it works fine. This is only from a terminated state.
It's extremely difficult to provide any debug information from Flutter from a terminated state.
I have gotten it working with a workaround. I introduced a 1 second delay before calling FirebaseMessage.instance.getToken();
You've likely got a race condition in there somewhere.

Any update on this? We are facing same issue

[benlc]

We're facing the same issue on iOS only it seems. I've been trying to reproduce this on through various scenarios, including going into airplane mode, and it seems like getInitialMessage is often empty on iOS but not on Android. We've verified codepath against firebase's doc like @keithcwk did

For me as well, both getInitialMessage and onMessageOpenedApp is not working. but onMessage is working fine.

Is there any solution for this problem?

This really needs to be looked into. This also happens to us in Release with Android. @Lyokone - Do you need additional information?

[Poloten]

Lyokone If I call FirebaseMessaging.instance.getInitialMessage().then((val) => .....) after few times later, (I mean some seconds), it works... In Main initState() - it doesn't work.
May be u can writter better bridge, like a stream ? Or maybe Future can't be resolved until message received if exist. Now it is unstable behaviour.

Upd: I debug that case. When Push received in terminated state, the application starts and call in the Main method InitState() without any click... I think it's not normal.

I have the same problem, Is there any solution for this?

[keithcwk]

Would like to humbly request for this issue to be investigated

While recently we haven't been noticing any null data being returned from getInitialMessage, we are currently facing issues where consumed initial messages are returned multiple times, similar to what is reported in the following issues

#12411
#10768

The code given in the example was able to replicate the outcome in release mode

[MattyBoy4444]

Do you need more information?

i think this issue related with #16853, #16871

#16871 (comment)

I just tried this, and it seems to be working fine.

  Future<void>.delayed(const Duration(seconds: 2), () async {
    final message = await FirebaseMessaging.instance.getInitialMessage();
    print('getInitialMessage($message)');
  });

});

This doesn't work for me at all. Everything works fine on Android tho. But this delay feels really hacky. Where do you have this logic? Somewhere after main.dart? No matter what I do, getInitialMessage is always null on iOS.

Flutter 3.23.4
firebase_messaging: ^15.1.5

The problem with iOS is that the initial notification is received in this delegate method handler: https://github.com/firebase/flutterfire/blob/main/packages/firebase_messaging/firebase_messaging/ios/firebase_messaging/Sources/firebase_messaging/FLTFirebaseMessagingPlugin.m#L224

We have no control over when that becomes available. I used the messaging example app. This call to getInitialMessage always returned null on app boot after opening from terminated state: https://github.com/firebase/flutterfire/blob/main/packages/firebase_messaging/firebase_messaging/example/lib/main.dart#L182

But If I press this button: https://github.com/firebase/flutterfire/blob/main/packages/firebase_messaging/firebase_messaging/example/lib/main.dart#L325

I received the initial notification. This is why this works:

There isn't anything we can do about this I'm afraid, we cannot get the initial notification until the system provides it. I would design your app with this consideration in mind.

I have tried to call this method inside of my initState:

  Future<RemoteMessage?> getInitialMessage() async {
    for (var i = 0; i < 10; i++) {
      var initialMessage = await FirebaseMessaging.instance.getInitialMessage();

      if (initialMessage != null) {
        return initialMessage;
      }

      await Future.delayed(const Duration(seconds: 1));
    }

    return null;
  }

However, even after all 10 tries i.e 10 seconds this is constantly returning me null. So I'm assuming the system never provides the initial message at all.

From the Cloud Messaging docs:

On iOS, if the user swipes away the application from the app switcher, it must be manually reopened for background messages to start working again.

I am indeed doing a release build, swiping to kill / terminate the app and then send a push and click on it to open app again. Could that be the reason this is happening? Or what is meant by the "background messages" in this context? Because all other handlers are working fine on iOS.
