pub get version solving failed for current firebase_storage ^10.0.1

🐛 Bug Report

It seems on flutter channel stable it is not possible to add flutter_cache_manager_firebase right now. Am I missing anything on my side?

Here are the details:

$ flutter pub add flutter_cache_manager_firebase
Because flutter_cache_manager_firebase >=2.0.0 depends on firebase_storage ^8.0.0 and flutter_cache_manager_firebase <2.0.0 depends on path_provider ^1.4.0, every version of flutter_cache_manager_firebase requires firebase_storage ^8.0.0 or path_provider ^1.4.0.
And because <project> depends on firebase_storage ^10.0.1, every version of flutter_cache_manager_firebase requires path_provider ^1.4.0.
So, because <project> depends on both path_provider ^2.0.2 and flutter_cache_manager_firebase any, version solving failed.
pub finished with exit code 65

Reproduction steps

flutter upgrade
flutter pub upgrade
flutter pub upgrade --major-versions

First of all

because <project> depends on (...) flutter_cache_manager_firebase any

I would never recommend depending on 'any'.

Because flutter_cache_manager_firebase >=2.0.0 depends on firebase_storage ^8.0.0 ...
And because <project> depends on firebase_storage ^10.0.1

This is the issue in this case, this has nothing to do with "flutter channel stable", but with your project also depending on firebase_storage version 10. Reading the changelog I think it doesn't have breaking changes for this package and should be able to support >=8 < 11 fine.

Sure, the any resulted from copying the output of flutter pub add flutter_cache_manager_firebase, sorry for that. For correctness, when adding

flutter_cache_manager_firebase: ^2.0.0

to the pubspec.yaml, the output of flutter pub get is:

$ flutter pub get
Because flutter_cache_manager_firebase >=2.0.0 depends on firebase_storage ^8.0.0 and <project> depends on firebase_storage ^10.0.1, flutter_cache_manager_firebase >=2.0.0 is forbidden.
So, because <project> depends on flutter_cache_manager_firebase ^2.0.0, version solving failed.
Running "flutter pub get" in <project>...
pub get failed (1; So, because <project> depends on flutter_cache_manager_firebase ^2.0.0, version solving failed.)

So, how would the version solving be fixed?

Reading the changelog I think it doesn't have breaking changes for this package and should be able to support >=8 < 11 fine.

Would it need an update in this package here?

Please bear with me, if the question sounds silly, still new to Flutter. :-)

Same issue here. The package dependencies requires an update.

@toebgen While waiting a new release, a workaround is to manually override the Firebase Storage dependency in your pubspec.yaml :

dependencies:
  [...]

dependency_overrides:
  firebase_storage: 10.0.1

I updated to the new dependency in flutter_cache_manager_firebase: ^2.0.1.
