what is benefit of using ( proguard-rules.pro ) and implementation "androidx.core:core-ktx:1.10.0"

I think ProGuard is something that would come when the project was created and has never been modified. R8 is more effective to reduce, obfuscate and optimise any flutter application. So ProGuard will be removed in favour of R8.

On the other hand I am very interested about your issue and I would like to ask you for more information about your error with "androidx.core:core-ktx:1.10.0", as well as the sdk and api versions you are using because as far as I can see it works. Could you give me more information?

Thank you very much for your contribution to the project.
