Nothing here at all for Flutter, just words.
I develop iOS, Android, Web and Mac apps, and I was honestly blown away by the quality of the intelliJ and VSCode plugins available for Flutter. In fact, they've kinda ruined me for other language SDKs now.
Granted, the lack of material, demos and discussions makes it difficult to tackle some problems, but that seems to be changing these days. It's hard NOT to enjoy coding in Flutter, though, and I think that end up being its biggest strength.
I can imagine they haven't had the time to flesh out docs yet.
