I’ve recently began developing with Flutter as well. Although I’m not sure about the community, but you’re right, the resources and guidance provided by Google are excellent especially for beginners.

There’s a lot more variety of learning resources compared to other languages; there are texts, workshops, videos, code labs, etc. It’s also nice seeing members of the Flutter team facilitate some of the workshops themselves; it’s refreshing to see developers being involved in educating users, instead of ‘outsourcing’ everything to others.
