⚠️ 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 build_runner
The current Dart SDK version is 3.5.4.

Because appainter depends on build_runner >=2.4.14 which requires SDK version ^3.6.0, version solving failed.


You can try one of the following suggestions to make the pubspec resolve:
* Try using the Flutter SDK version: 3.27.2. 
* Consider downgrading your constraint on build_runner: flutter pub add dev:build_runner:^2.4.13
