FlutterFlow cofounder here! We thought the HN crowd would want to see the generated code for FlutterMet, so here it is: https://github.com/FlutterFlow/FlutterMetSample/tree/flutter... We try to generate clean Flutter code that follows best practices – we have a long way to go, but we couldn't be more excited. Edit: Also, here's the video of us building it (in just under an hour): https://youtu.be/TXsjnd_4SBo
I'm excited to see desktop applications built using FlutterFlow as desktop support for flutter is fast improving.
P.S. I've added FlutterFlow to my curated list of startup tools - https://startuptoolchain.com/ under Visual Programming. I wish you all the best.
