⚠️ 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 intl
Because dart_code_metrics >=5.7.0 depends on http ^0.13.5 and dart_code_metrics >=4.20.0 <5.7.3 depends on pub_updater ^0.2.2, dart_code_metrics >=4.20.0 requires http ^0.13.5 or pub_updater ^0.2.2.
And because pub_updater <0.3.1 depends on http ^0.13.3 and intl >=0.20.0 depends on http ^1.0.0, dart_code_metrics >=4.20.0 is incompatible with intl >=0.20.0.
So, because rubik_utils depends on both intl ^0.20.0 and dart_code_metrics ^5.6.0, version solving failed.


You can try one of the following suggestions to make the pubspec resolve:
* Consider downgrading your constraint on dart_code_metrics: flutter pub add dev:dart_code_metrics:^4.19.2
* Consider downgrading your constraint on intl: flutter pub add intl:^0.19.0
