Error running pod install
Error launching application on iPhone 12 Pro.

When I try to run via external terminal then it works fine

I already try to run export UTF-8 command but nothing happens.

How can I resolve this issue? Hope you get my question. Thank you

Delete the Podfile, Podfile.lock, Pods folder, Runner.xcworkspace, Flutter.framwork(in ios/Flutter folder)

flutter clean

flutter build ios

OR Try This

rm ios/Podfile
flutter pub upgrade
flutter pub run
cd ios
pod init
pod update
flutter clean && flutter run

CodePudding user response：

Do following steps:

From xcode -> open preferences 
-> location -> 
Derived Data -> 
move to bin and remove it from Bin as well.

from android studio -> bottom panel -> Terminal -> enter following commands
-> flutter clean 
-> flutter pub get
-> cd ios [if not navigated to ios folder in flutter project]
-> pod install
-> pod update

now, run the app from android studio.

you will be able to run now.
