Add CI workflow to run Flutter unit tests on PRs to master #132
Description
We don’t have CI running Flutter tests on pull requests into master. Create a GitHub Actions workflow that runs flutter test on a GitHub-hosted runner for every PR targeting master (and on pushes to master), caches dependencies, and uploads coverage as an artifact. I’ll make the workflow a required check via branch protection after it’s merged.
Acceptance criteria:
- A file .github/workflows/flutter-tests.yml is added.
- Opening a PR against master runs a single job called flutter-tests on ubuntu-latest.
- The job caches dependencies between runs.
- The job executes flutter test --coverage, fails the workflow on failing tests, and uploads coverage/lcov.info as an artifact.
- The job runs on pushes to master as well.
- Concurrency prevents duplicate runs on the same ref.
Notes
- Only unit tests are needed (no emulators, no integration tests).
- I’ll configure Settings → Branches → Branch protection for master to require the flutter-tests check after this is merged.
