[firebase_messaging] Flutter 1.12.13+hotfix.5 Unresolved supertypes FlutterFirebaseMessagingService

[01FC]

After the latest Flutter stable update Flutter 1.12.13+hotfix.5 and trying to update the plugin to firebase_messaging: ^6.0.9 and the gradle configurations (3.5.3 and google services 4.3.2) there is an error that brakes the gradle assembly.

Supertypes of the following classes cannot be resolved. Please make sure you have the required dependencies in the classpath:
    class io.flutter.plugins.firebasemessaging.FlutterFirebaseMessagingService, unresolved supertypes: com.google.firebase.messaging.FirebaseMessagingService

It was working fine in the previous flutter stable version 1.9.4+hotfix.6 and the previous plugin version and gradle configurations.

Hi @01FC
can you please provide your updated flutter doctor -v
and your flutter run --verbose?
Also, to better address the issue, would be helpful
if you could post a minimal code sample
or the steps to reproduce the problem.
Thank you

@iapicca I am getting the same issue. I just created a new project and added firebase_messaging and build fails because of this.

Launching lib\main.dart on AOSP on IA Emulator in debug mode...

Has this been fixed yet? I'm having this issue too

Hey all 👋

As part of our roadmap (#2582) we've just shipped a complete rework of the firebase_messaging plugin that aims to solve this and many other issues.

If you can, please try out the dev release (see the migration guide for upgrading and for changes) and if you have any feedback then join in the discussion here.

Given the scope of the rework I'm going to go ahead and close this issue in favor of trying out the latest plugin.

Thanks everyone.
