I am facing an issue in flutter for a couple of days
before I close Android Studio everything was working fine with no errors so far, next day I started it with no changes, and it shows me an error message and cannot compile while there is no errors in my code or in anything

I had lots of reference of '.r' through my flutter app and I replaced all '.r' references with '' empty string and I came to to know that dart files also have been modified and now I get these errors in my debug console. I tried to fix these but seems like re-adding '.r' isn't fixing these problems.

Well, I hate bringing you bad news, but Flutter received a LOT of updates. You might want to either
Use an older version of Flutter (see: THIS LINK)
Refactor your code to adhere to the changes
