What teams ask before they build on our packages.

Short answers before you add them to your pubspec.

01 Can we use these packages in a commercial app?

Yes. Very Good CLI, very_good_analysis, formz, and the rest of our published packages are MIT-licensed, so you can use, change, and ship them in commercial apps.

02 Who maintains them?

VGV engineers, with help from the community. 100 people outside VGV have contributed, and about 100 pull requests get merged a month.

03 Does Very Good CLI run in CI?

Yes. Where a global install isn't possible, run any command with dart pub global run very_good_cli:very_good. very_good_workflows gives you ready-made GitHub workflows for the same checks.

04 Where do we report a bug or ask for a feature?

Open an issue on the package's GitHub repository. Pull requests are welcome too, from a typo fix to a new template.

05 Can VGV help our team adopt them?

Yes. Flutter Enablement is hands-on training, code review, and architecture guidance inside your repo, until your engineers ship to the VGV standard on their own. The first call is where we work out how that would look for your team.
