Google Sign In Failed

[Mark]

I want users to be able to sign in through Google in my app. I’m trying with Firebase Auth, I enabled the Google Provider in Firebase, and filled in the Firebase Core component, however whenever I try to log in it returns the error “Google Sign In Failed”.

I tried many ways and none of them worked, these are my blocks.

Initialize Firebas Auth on screen initialize.

Example :
When screen1 initialize
Initialize firebase auth > core1

When button1 click
Google signin > obfocus text.
