flutter Simulator doesn't work on android studio but works through Xcode-CodePudding

its a strange issue, when I build and run app on simulator via android studio, I get the following error:

Launching lib/main.dart on iPhone SE (2nd generation) in debug mode... Upgrading AppFrameworkInfo.plist Running pod install... CocoaPods' output: ↳ CDN: trunk Relative path: CocoaPods-version.yml exists! Returning local because checking is only performed in repo update

Error output from CocoaPods:

Error running pod install
Error launching application on iPhone SE (2nd generation).

but when I build from Xcode, it builds perfectly.

CodePudding user response：

i got a brief solution to my question. after running the following commands one by one:

flutter clean
rm -Rf ios/Pods
rm -Rf ios/.symlinks
rm -Rf ios/Flutter/Flutter.framework
rm -Rf ios/Flutter/Flutter.podspec
flutter pub get
cd ios
pod install
arch -x86_64 pod install (On an M1 mac use => arch -x86_64 pod install)

here if you get UTF-8 error then run this command

export LC_ALL=en_US.UTF-8

and run arch -x86_64 pod install (On an M1 mac use => arch -x86_64 pod install) command again.

finally run flutter run command to start the simulator
