Answer 1

I think it has to do with your podfile , try removing the podfile & podfile.lock (move it elsewhere so you can move it back if needed), it will build itself again. I also wouldn't ignore all the deprecated warnings in your stead.

Answer 2

Have you had the opportunity to try building on a physical device?

Try changing the flutter channel and cleaning the project and pods. It usually works for me when I can't build for iOS.
