词法或预处理器问题（Xcode）：找不到“Flutter/Flutter.h”文件

Question

I'm working on a project of a team and get this error when i try to debug.

My flutter doctor found no issue and I am not familiar with the code since I get the project repo from someone else.

Launching lib/main.dart on iPhone 13 in debug mode...
lib/main.dart:1
Xcode build done.                                            1.8s

Could not build the application for the simulator.
Error launching application on iPhone 13.
Exited (sigterm)

EDIT:
After I deleted the derived data and tried: flutter clean > flutter pub get > cd ios > pod install > pod update and try to build the app again, i get the same error.

Answer 1

Ran into this issue myself, all SO answers seem to point towards cleaning, pod install,... The correct answer is buried deep in the Flutter

However, this is caused by the checkbox "For install builds only" on the "Run Script" inside of the Xcode project Build Phases for the target Runner. This needs to be unselected .
