Unhandled Exception: DatabaseException(Error Domain=FMDatabase Code=26 "file is not a database". After updating to Flutter 2.0

Question

I tried to update Flutter to version 2.0.5 and Dart language from 2.10.4 to 2.12 version since from that moment I had a lot of errors.

I tried several ways including re-installing Pods and also to go back to the previous Flutter version but now I get an error when running in iOS only (not in Android!).

I would enourmously appreciate if you could help me in some way.

This is the error message in the console:

Try running pod update in your pod file
