Johan, I have been following and coding along every flutter video class. It's amazing to see that my little apps are running on my device (connected via usb). It's has been a great experience so far and as usual, thanks a Million.
I've just updated to an M1 iMac but none of the reviews I looked prepared me for the complete lack of Android support for Flutter on the M1, no emulators and I can't get a USB attached Android handset to work either. So it's down to IOS simulator's which to be honest seem a bit 'flakey', for instance the keyboard that displays for text entry stops being displayed after a while and needs a simulator reload to fix it.
Oops, not good. Keep us updated here if you found a solution. I can unfortunately not help as I do not have an M1 Mac of any sorts. Maybe run Win on Parallels on your Mac until everything is working better.: www.parallels.com/pd/general/?gclid=Cj0KCQjwraqHBhDsARIsAKuGZeGOdVckXSOdEOwiBaLsQdIsjuYqVTkuVqHe3R2vcKl6C8XSWXY1UcgaAkEGEALw_wcB
