Flutter unique_identified library issue? - ios

Question

I have a problem that when I used a library for flutter application to get the unique_id a problem arose where I can't do the build due that x-code can't import the required libraries even after pod installation was successful ,
Here is a screenshot of what the error would look like :
here is the exception stack trace when doing dart build :
Launching lib/main.dart on iPhone XR in debug mode...
Running pod install...
Starting Xcode build...
Xcode build done. 41.0s
Failed to build iOS app
Error output from Xcode build:

*** Update on the above [ the error above was corrected by removing the file and adding them again manually but now another problem appeared , when the code that get the unique Identifier is called exception happen ]
I appreciate the help
