ITMS-90863: Apple silicon Macs support issue

I've got this email when I am publishing app to AppStore (or TestFlight).

How may I solve it?

Found a hint here https://developer.apple.com/forums/thread/735610, the main cause is that the iOS code still catches and throws FlutterErrors. After we got rid of that in our fork everything worked again. Here is the commit: https://github.com/wearnotch/flutter_blue/commit/4a0cad8ac8417a4460b4230a9429f58276696422 (sorry there are a lot of indentation changes as well)

update to latest flutter_blue_plus and it will resolve this issue as well
