google_sign_in library

System-browser Google sign-in for Flutter. The widget-free core.dart keeps its injectable browser port and never imports native platform channels.

Classes

FFXGoogleSignInBrowser

A system-browser port. The browser returns the final app URL, never a Google token.

FFXSystemGoogleSignInBrowser

Construct in the sign-in button handler, before any await, so web popups retain the browser's user gesture. Native apps use the OS authentication browser and never an embedded WebView.
