🐛 [firebase_messaging] getInitialMessage() does not terminate on macOS if app starts from terminated state

[Lootwig]

Bug report

The method works as expected on iPad, but on macOS any code after getInitialMessage() is never executed.

Steps to reproduce

Steps to reproduce the behavior:

1. Add any behavior after await FirebaseMessaging.instance.getInitialMessage(), e.g. showDialog()
2. Close app and trigger a push notification
3. Click notification: App opens, but the behavior from 1. is never observed

Sample project

Configure this project with flutterfire configure, set up XCode for signing etc.

Thanks for the report @Lootwig Per this documentation for macOS, can you confirm if the required permissions are configured properly ?

[Lootwig]

@darshankawar The suggested default parameters are exactly the ones I left in the requestPermission() call. I am receiving the notification and it opens the app just fine. It's just the mentioned callback that doesn't terminate as it does on iPad and Android.

Thanks for the update. Using the repo provided, I seem to be able to replicate the reported behavior.
