Question

So I was running my application fine as a Chrome instance with the code below.

void main() async {
  WidgetsFlutterBinding.ensureInitialized();

  // Check if the app is running on the web
  if (kIsWeb) {
    print("Running on Web - Initializing Firebase...");
    try {
      await Firebase.initializeApp(
        options: DefaultFirebaseOptions.currentPlatform,
      );
      print("Firebase initialized successfully for Web.");
    } catch (e) {
      print("Error initializing Firebase for Web: $e");
    }
  } else {
    print("Not running on Web - Firebase functionality disabled.");
  }

  runApp(
    DevicePreview(
      enabled: !kReleaseMode, // Enabled only in development mode
      builder: (context) => const MyApp(), // Wrap your app
    ),
  );
}

Then, I decided to add a Firebase Test Suit and modified my code, following the documentation:

void main() async {
  WidgetsFlutterBinding.ensureInitialized();

  if (kIsWeb || Platform.isIOS || Platform.isAndroid) {
    print("Running on Web/iOS/Android - Initializing Firebase...");

    if (kDebugMode) {
      try {
        FirebaseFirestore.instance.useFirestoreEmulator('localhost', 8080);
        await FirebaseAuth.instance.useAuthEmulator('localhost', 9099);
        print(
            "Firebase initialized successfully - DEVELOPMENT -  for Web/iOS/Android.");
      } catch (e) {
        print(e);
      }
    } else {
      try {
        await Firebase.initializeApp(
          options: DefaultFirebaseOptions.currentPlatform,
        );
        print(
            "Firebase initialized successfully - PRODUCTION -  for Web/iOS/Android.");
      } catch (e) {
        print(e);
      }
    }
  } else {
    print("Not running on Web/iOS/Android - Firebase functionality disabled.");
  }

  runApp(
    DevicePreview(
      enabled: !kReleaseMode, // Enabled only in development mode
      builder: (context) => const MyApp(), // Wrap your app
    ),
  );
}

and now, in the IDE I get no errors and it should be running fine, but I get this kind of error, and I am not sure how to fix it:

Can somebody help me resolve this issue, please? I suspect it has something to do with those libraries, but not sure
