Will do! Any specific things you like to see in workflow vids? Otherwise I'll just do the obvious stuff. I will reply here when I have something for y'all.
The tl;dr is, on the Mac, (1) start their Simulator app; (2) start a build with watch in the app root directory; and (3) edit code as usual (IntelliJ/Cursive).
The app rebuilds/reloads on save. Tensegritics is looking at better hot reloading; I am happy with automatic full restarts.
Flutter offers a couple of endpoints to visit for debuggers, but I just live off print debugging in the build console.
Please let me know what else you might like to see.
