title: Did anyone manage to get the id token from google sign in (Flutter)
body: <p>I am trying to connect my users with my back end server , i used the example from the official google sign in plugin for flutter :
  <a href="https://pub.dartlang.org/packages/google_sign_in" rel="noreferrer">https://pub.dartlang.org/packages/google_sign_in</a></p>
  
  <p>the sign process goes fine and i get the username and email ect..
