Example

shorebird_ci.yaml is the workflow shorebird_ci generate produces for a minimal Dart workspace with two packages — app (depends on core) and core:

my_repo/
  pubspec.yaml          # workspace root
  packages/
    app/pubspec.yaml    # depends on core
    core/pubspec.yaml

Reproduce it with:

dart pub global activate shorebird_ci
shorebird_ci generate --repo-root . --dry-run

The workflow has two jobs. setup activates shorebird_ci on the runner, calls verify to fail fast if CI coverage has drifted from the dep graph, then calls affected_packages to emit the JSON matrix. dart_ci fans out across that matrix, running format / analyze / test for each affected package — including transitive dependents (a change to core runs app too).

For Flutter packages a parallel flutter_ci job is added, with flutter_version resolved from the pubspec when pinned. With codecov configured, coverage upload steps are added. With a cspell config present, a cspell job is added. None of those apply to this minimal example.

See the package README for the static (--style static) variant and other options.
