Angular alpha and beta releases are production quality
Google thoroughly tests each version of AngularDart—even alpha releases—to ensure that our mission-critical apps that depend on Angular continue to work well.
The alpha label indicates that the API is changing, and that the release (or a release after it) might break your code.
For more information, see the documentation for the pub version scheme.
