Terminal output is:

I'm using the stable version of flutter 1.12.13+hotfix.9, and this issue appears only on ios building.

How can I solve this issue?

I've just managed to solve this issue. I've just followed advise https://github.com/flutter/flutter/issues/29974 and added "$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" embed to Run script Run script After rebuilding App.framework folder has been added to build directory and problem has gone. Hope this will help someone else.

First, you should write in your android studio terminal this command:

  • rm -rf ios/Flutter/App.framework

  • Then in Xcode select TARGETS then select Runner

  • After that choose the Build Phases from Middle Top options

  • Then Open the Thin Binary

  • Remove the script inside with

/bin/sh "$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" embed

/bin/sh "$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" thin

That's Worked for me, Hopefully, work for you also :-)

In my case, I need to uncheck the build flag "For install build only" in Build Phrases -> Run Script
