desktopSignIn method

@override void desktopSignIn(AuthAction action)

Handles authentication logic on desktop platforms

Implementation

@override
void desktopSignIn(AuthAction action) {
  // google_sign_in supports macOS, so mobile auth flow works.
  if (defaultTargetPlatform == TargetPlatform.macOS) {
    mobileSignIn(action);
  } else {
    super.desktopSignIn(action);
  }
}
