Congrats! I like your enthusiasm and very much understand.

Last time i programmed in Dart it was chess rules&multiplayer both client and server (https://peerchess.com/). I have strong “PHP love&Javascript hate” background and even if i cant work in Dart for living it is best language and ecosystem I’ve ever known. I hope and wish that one day it will be as popular as js, but it seems rather harder and harder become mainstream…
