Update Code

In the beginning of the method build of the widget that requires authentication (it should be stateful), add the code:

if (faui.User == null) {
  return faui.BuildAuthScreen(
    onExit: this.setState((){...}),
    firebaseApiKey: "...",
  );
}

Get user email:

faui.User.email

Sign out:

faui.SignOut()

Silent sign-in:

// Before runApp:
WidgetsFlutterBinding.ensureInitialized();
await faui.TrySignInSilently(firebaseApiKey: '...');
...

// After sign in with dialog:
faui.SaveUserLocallyForSilentSignIn();
