Command PhaseScriptExecution failed with a nonzero exit code, build app - ios

Question

I m try in to build an Ios app made with Flutter and Dart ( I did not program it)
But i have this error Command PhaseScriptExecution failed with a nonzero exit code
I don t really understand why, because in the details as seen here, i only have some warnings but no errors.
As i didn t programm it , i don t really know how to handle this, any idea please?
i m using
xcode 12.4
Flutter 2.0.6
Dart 2.12.3
The answers i found related to similar topics didn´t really help me
here the detailled output
