Complete CI/CD for Flutter Apps

My Workflow

This GitHub Action workflow can be used to fully automate your build, test and deployment processes for Flutter.
All Flutter build targets are supported with this workflow: android, iOS and web.
When pushing without a tag this workflow will analyze and test your Flutter app.
When pushing with a tag (starting with 'v' in this case) this workflow additionally creates a release including all artifacts needed for deployment.
These artifacts can then be used to deploy your apps.
I have added the firebase hosting deploy as an example for web deployment.

This can be further extended to deploy the iOS and Android app to a test platform like testflight or directly to the platform specific stores (don't forget to sign your apps 😄).

This workflow is a great starting point for any Flutter app and can be tweaked to your personal preference.

Additional Resources / Info

We currently use this workflow for our own Flutter app that is not yet published and not yet open-source, but are planning on doing so in the near future!
