Flutter FirebaseError: Firebase: firebase.auth() takes either no argument or a Firebase App instance. (app/invalid-app-argument)

I have created a firebase email/password auth and it was working fine until today. Sign up and sign in stopped working and I tried flutter clean and re running it. The code hasnt changed as I tried reverting to an older version of the app and it still gave the same error. Here are some more details: FirebaseError: Firebase: firebase.auth() takes either no argument or a Firebase App instance. (app/invalid-app-argument).

This is my button

ElevatedButton(
  style: buttonStyle,
  onPressed: () async {
    if (_formKey.currentState!.validate()) {
      try {
        final credential = await FirebaseAuth.instance
            .signInWithEmailAndPassword(
          email: _emailController.text,
          password: _passwordController.text,
        ).then((_) {
          Navigator.pushReplacementNamed(context, '/timeline');
        });
      } on FirebaseAuthException catch (e) {
        if (e.code == "invalid-email") {
          showDialog(
            context: context,
            builder: (context) => ErrorMessage("Invalid email"),
          );
        } else if (e.code == 'user-not-found') {
          showDialog(
            context: context,
            builder: (context) => ErrorMessageWithRoute(
              "Email not registered",
              "/signup",
            ),
          );
        } else if (e.code == 'wrong-password') {
          showDialog(
            context: context,
            builder: (context) => ErrorMessage("Wrong password"),
          );
        }
      } catch (e) {
        showDialog(
          context: context,
          builder: (context) => ErrorMessage(
            "There was an error please contact us or try again ${e}",
          ),
        );
      }
    }
  },
  child: const Text("Sign in"),
);

The catchall at the end is what is running and telling me the error. Here are my firebase options I removed all the values but left the keys for security:

The domain I am running it on is localhost 5000 and I allowed it in the google cloud apis and services

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(
    options: DefaultFirebaseOptions.currentPlatform,
  );
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'FBLA Lettering Points',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      routes: <String, WidgetBuilder>{
        '/signin': (context) => const SignInPage(),
        '/signup': (context) => const SignUpPage(),
        '/timeline': (context) => const Timeline(),
        '/profile': (context) => const Profile(),
        '/verify': (context) => const VerifyEmailPage(),
      },
      home: const SignInPage(),
    );
  }
}

I figured out the issue, I tried updating my package numbers in pub.dev and this worked.
