Having an issue authenticating google sign in with flutter
So I'm trying different approaches to make authentication with flutter to work with no success.
Before posting the code it's important to say that I couldn't make the google services 4.3.3 work with any Gradle version so I have changed the versions to Gradle 3.2.1 and google services to 4.2.0 and I checked connectivity with firebase and it works. Plus, I added SHA1.
I can't track the error causing the application to fail and it's not the first post I have uploaded about it and I have searched online so many solutions with no success.
