Flutter ios app is not running (Error (Xcode): Undefined symbols)

I have been trying to run my app for a long time, and I have tried many things but I could not run it. I have tried to update some packages, run older versions of the app, update Flutter SDK, update Xcode, my MacOS but nothing really worked.

This is the error I am getting.

I have also tried

flutter clean
rm -rf Pods Podfile.lock
pod repo update
pod deintegrate
pod update
rm -rf ~/Library/Developer/Xcode/DerivedData/
pod deintegrate
pod install 

I also ran flutter doctor and all seems good. I have even tried creating another project to test it and it worked without any issue.

But for this project, unfortunately, nothing worked for me. So does anyone know what might be the issue and how to solve it?
