Firebase packages incompatibility

[lukeurban]

I am working on the app which uses:

  firebase_analytics: ^6.3.0
  firebase_messaging: ^7.0.3

I wanted to add firebase_crashlytics: 0.4.0+1 to it, but it seems I have a problem with dependency versioning.

And because no versions of firebase_messaging match >7.0.3 <8.0.0, firebase_crashlytics >=0.4.0 <0.5.0-1.0.nullsafety.0 is incompatible with firebase_messaging ^7.0.3.

When I wanted to find a fitting firebase_messaging version I was a little suprised that the last two versions: 9.0.0 and 7.0.3 are not fitting >7.0.3 <8.0.0 requirements.

I am not able to upgrade to Flutter 2.0 due to dependency problems with certain packages Flutter#77491.

Is there a good solution to mentioned dependency problem?
Thanks,
L
