I tried to restart, search, and made everything but then nothing worked for me
Does anybody have an idea why is that happening?
thanks in advance
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.

Basically the awesome notifications is trying to access "DecoderBufferCallback" variable from the flutter library but sadly in the flutter library they changed that variable name to "DecoderCallback"...
SO you need to actually edit the variable name in the library code of AwesomeNotifications from "DecoderBufferCallback" to "DecoderCallback".. This is their job but we are doing it for them
P.S.: I know the awesoome notifications version is older in this screenshot but i just wanted to show where to do the edit... so i opened up an older project
I would like to start a Flutter counter app. So I prepared all and started the flutter counter project.
Then I got this error:

I already tried everything within the following error question on "Execution failed for task ':app:compileFlutterBuildDebug'." error message until Jakub S. answer to remove .gradle folder.
how to solve Execution failed for task ':app:compileFlutterBuildDebug'
Currently I think the problem is with the '"GenerateAppTitle" not found' message.
I tried the counter app on VS Code and Android Studio.
Nothing worked. What could the solution be?
I created and run a location and weather based app. But when I closed the VS Code and try to reinstall the app, the following error occurred!.
How to remove the error!.
