Great, I will work on a PR and push it soon.

• Preparing environment
  • Cloning repository
  • Setting up dev environment
• Working on changes
• Reviewing changes
• Opening pull request

I've opened a draft pull request: #134

The coding agent reported the work is incomplete: Code and tests are fully implemented, but analyze/tests could not be run because the provided Flutter SDK (Dart 3.12.2) is older than the repo's required ^3.13.0.
