Do you have any pointers for someone who would love to contribute to Flutter and Dart as an open source contributor? Is there some guideline for what kind of contributions will be considered, areas where contributions are desired, etc?

We've got a guide here that covers some of these areas: https://github.com/flutter/flutter/blob/master/CONTRIBUTING....

For a lot of first-time contributors, improved documentation and added tests are a great way to dip toes into the water. We also have a 'good first contribution' tag on our issues log that might be a source of inspiration: https://github.com/flutter/flutter/issues?q=is%3Aopen+is%3Ai...

I'll mark the "better tell Tim" about the HN article off my list. :)

Awesome, thanks!

Please check the contribution guide: https://github.com/flutter/flutter/blob/master/CONTRIBUTING....

We strive to be an open community. Anyone can become a Flutter team member if they contribute frequently :)

Thank you! I think that's a great attitude and a key to the long-term success.
