Reproduces using the package code sample. It may not fit properly in light mode as well, but it is visible in dark mode.

code sample

import 'package:firebase_core/firebase_core.dart';
import 'package:firebase_ui_auth/firebase_ui_auth.dart';
import 'package:firebase_ui_oauth_google/firebase_ui_oauth_google.dart';
import 'package:flutter/material.dart';

import 'firebase_options.dart';

Future<void> main() async {
    WidgetsFlutterBinding.ensureInitialized();
    await Firebase.initializeApp(options: DefaultFirebaseOptions.currentPlatform);

    FirebaseUIAuth.configureProviders([
        GoogleProvider(clientId: 'clientId'),
    ]);

    runApp(MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key}) ;

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      theme: ThemeData(brightness: Brightness.dark),
      home: SignInScreen(
        actions: [
          AuthStateChangeAction<SignedIn>((context, state) {
            // redirect to other screen
          })
        ],
      ),
    );
  }
}
