⚠️ 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: example/pubspec.lock

Command failed: flutter pub upgrade riverpod_generator
Because riverpod_generator >=4.0.3 depends on riverpod_annotation 4.0.2 and example depends on riverpod_annotation ^2.3.5, riverpod_generator >=4.0.3 is forbidden.
So, because example depends on riverpod_generator 4.0.3, version solving failed.


You can try the following suggestion to make the pubspec resolve:
* Consider downgrading your constraint on riverpod_generator: flutter pub add dev:riverpod_generator:^2.4.0
Failed to update packages.
