Answer 1

There could be many reasons for such a error. I had a similar error. I would suggest you to open your project in android studio and check your gradel versions. I see by the name of you app that you are using firebase. Some of those plugins use Androidx. So migrating your project to Androidx might help. Here's how to migrate your project to Androidx.

Hope it helps!

Answer 2

I had the same issue this may because of the incompatibility of Gradle versions.

I opened the android part in Android Studio and updated Gradle as recommended by Android Studio with Alt+Enter and it solved my problem.

I can elaborate more if you can post more details about it eg your app/gradle file.
