Flutter app, cannot build the app in simulator - iphone

Question

First time posting on stackoverflow. I feel like I'm entering into the "club" lol.
So I'm trying to launch this flutter app on iOS (app already on Google Play).
But somehow, I can't run my app on my iOS Simulator, idk why.
the first review of apple was about a crash happening when they try to do a selfie (as required in the app).
flutter doctor is all OK
Here is what I obtain when I do flutter run output in my terminal:
Launching lib/main.dart on iPhone 13 in debug mode... Running pod

Thanks for your help

Answer 1

Remove ios/Flutter/Flutter.podspec: rm ios/Flutter/Flutter.podspec
Run flutter clean
Run your app again.
