⚠️ Artifact update problem

Renovate failed to update an artifact related to this branch. You probably do not want to merge this PR as-is.

♻ Renovate will retry this branch, including artifacts, only when one of the following happens:

• any of the package files in this branch needs updating, or
• the branch becomes conflicted, or
• you click the rebase/retry checkbox if found above, or
• you rename this PR's title to start with "rebase!" to trigger it manually

The artifact failure details are included below:

File name: pubspec.lock

Command failed: flutter pub upgrade firebase_crashlytics
Because firebase_crashlytics >=4.0.0 depends on firebase_core ^3.0.0 and the_app depends on firebase_core ^2.15.0, firebase_crashlytics >=4.0.0 is forbidden.
So, because the_app depends on firebase_crashlytics ^4.0.0, version solving failed.


You can try the following suggestion to make the pubspec resolve:
* Consider downgrading your constraint on firebase_crashlytics: flutter pub add firebase_crashlytics:^3.4.0
