Flutter - iOS: Command /bin/sh failed with exit code 255

Question

Good afternoon,

I try to run a Flutter project on iOS, previously successfully run on Android. However, I got an error:

\"x86_64\" is not an allowed valu         


        

Answer 1

After lots of try i follow these steps to release ipa file :

1. Go to your trminal:
2. cd your-flutter-project
3. flutter run (That will launch the app to your connected or opened device )

Now, come to again to your MAC terminal and type

• flutter build apk (that will make the release apk)

For IOS,

• flutter build ios

after complete the task you will see the path of your file package something like

/Users/Sanjeev/Documents/WorkSpaceForFlutter/myapp/build/ios/iph oneos/Runner.app.

Now go to Xcode >Product >Archive you will get the screen below

This is how i resolve my issue Command /bin/sh failed with exit code 255
