(Macbook M1 Pro) flutter run problem with cocoapods - ios

Question

After installing the camera dependancy and running flutter run on my new Macbook M1, i got problems with cocoapods, which I successfully installed.
After trying the recommended command "gem pristine ffi --version 1.15.5", i received no error:
output:
Restoring gems to pristine condition...
Building native extensions. This could take a while...
Restored ffi-1.15.5
But when running flutter run I got the same error
flutter run output:
`
Launching lib/main.dart on iPhone 14 Pro Max in debug mode...
Running pod install... 668ms

I tried reinstalling cocoapods and ffi several times, also using sudo gem install cocoapods
sudo arch -x86_64 gem install ffi
