Unable to create new user on firebase with createUserWithEmailAndPassword()

[sillyjohn]

I have been following a tutorial on how to create a register screen, however, whenever I click the register button, the following error shows up. I am using VScode and ios 17.5 emulator for this project.
Code:

import 'package:flutter/material.dart';
import 'package:firebase_core/firebase_core.dart';
import 'package:firebase_auth/firebase_auth.dart';
import 'firebase_options.dart';

void main() async{
  WidgetsFlutterBinding.ensureInitialized();
  runApp( MaterialApp(
      title: 'Flutter 1',
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home: const HomePage(),
    ));
}

class HomePage extends StatefulWidget {
  const HomePage({super.key});

  @override
  State<HomePage> createState() => _HomePageState();

}

class _HomePageState extends State<HomePage> {
  late final TextEditingController userEmail;
  late final TextEditingController userPassword;

  @override
  void initState() {
    // TODO: implement initState
    userEmail = TextEditingController();
    userPassword = TextEditingController();
    super.initState();
  }
  @override
  void dispose() {
    // TODO: implement dispose
    userEmail.dispose();
    userPassword.dispose();
    super.dispose();
  }
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Login'),)
        ,
        body: FutureBuilder(
          future: Firebase.initializeApp(
                options: DefaultFirebaseOptions.currentPlatform,
          ),
          builder: (context, snapshot) {
            switch (snapshot.connectionState){
              case ConnectionState.done:
               return Column(
                      children: [
                        TextField(
                          controller: userEmail,
                          keyboardType: TextInputType.emailAddress,
                          decoration:const InputDecoration(
                            hintText: 'Email Address')
                        ),
                        TextField(
                          controller: userPassword, 
                          obscureText: true,
                          enableSuggestions: false,
                          autocorrect: false,
                          decoration:const InputDecoration(
                            hintText: 'Password')
                        ),
                        TextButton(
                        onPressed: () async {
                          final emailEntered = userEmail.text;
                          final passwordEntered = userPassword.text;
                          await FirebaseAuth.instance.createUserWithEmailAndPassword(
                              email: emailEntered,
                              password: passwordEntered
                            );
                        }, 
                        child: const Text('Register')
                        ),
                      ],
                      );
               default:
                  return const Text('Loading...');   
            }
                     },
        ),
    );
  }
}
