SignInWithGoogle crashes on Android

I'm getting this exception on android 9.0 with latest version of this plugin:

I'll take a look right away.

I don't readily see it being an issue with SignInWithGoogle itself.

The error message appears instead to be concern with AndroidX.

I'll leave it to you to research this further on your own: "Failed resolution of: Landroidx"

Stackoverflow is a great resource: site:stackoverflow.com "Failed resolution of: Landroidx"

Github has its uses as well: site:github.com "Failed resolution of: Landroidx"

Hi, sorry I was wrong: it was related to my project libs. I solved it by recreating the project.
Thank you
