⚠️ 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 flutter_lints
Because app_mc depends on flutter >=3.7.0 <=3.16.0 from sdk which doesn't match any versions, version solving failed.


You can try the following suggestion to make the pubspec resolve:
* Try updating the following constraints: flutter pub add cupertino_icons:^1.0.5 flutter:'{"version":"^0.0.0","sdk":"flutter"}' dev:flutter_lints:^6.0.0 dev:flutter_test:'{"version":"^0.0.0","sdk":"flutter"}'
