Install and run Locally

flutter pub global activate license_checker_for_github_action

  • Make sure you are in the main directory of your Flutter app or Dart program
  • Execute dart_license_checker

If this doesn't work, you may need to set up your PATH (see https://dart.dev/tools/pub/cmd/pub-global#running-a-script-from-your-path)

Github action

  - name: Check licenses install 
    run: | 
      dart pub global activate license_checker_for_github_action 
  - name: Check licenses
    run: | 
      dart_license_checker

Showing transitive dependencies

By default, dart_license_checker only shows immediate dependencies (the packages you list in your pubspec.yaml).

If you want to analyze transitive dependencies too, you can use the --show-transitive-dependencies flag:

dart_license_checker --show-transitive-dependencies

If you want to output only copyleft dependencies use --only-copyleft flag:

dart_license_checker --only-copyleft

If you want to output an error if your licenses contain a copyleft license (such as in a github action) add --fail-on-copyleft flag:

dart_license_checker --fail-on-copyleft

In conjunction with --only-copyleft or --fail-on-copyleft flag, you might want to ignore some libraries. To do this use --ignores:

dart_license_checker --fail-on-copyleft --ignores 'nm, lib2'
