Xcode – Command PhaseScriptExecution failed with a nonzero exit code when flutter run in debug

I have a Flutter project which runs perfectly in v2.3.3. I upgraded the flutter version to 3.0.0 in order to use null safety feature. I solved every errors. However when I ran the project, I got Command PhaseScriptExecution failed with a nonzero exit code error. I couldn’t find any reasonable and logical solutions throughout internet. Could you please help me on this issue?
