Flutter internal error while using signInWithEmailAndPassword

I’m trying to create a sign-in form using flutter and firebase. I’m facing the following error while using the signInWithEmailAndPassword function:

[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: [firebase_auth/internal-error] An internal error has occurred, print and inspect the error details for more information.

Code:

body: Column(children: [
          TextField(
            controller: _email,
            keyboardType: TextInputType.emailAddress,
            enableSuggestions: false,
            autocorrect: false,
            decoration: const InputDecoration(
              border: OutlineInputBorder(), hintText: "Email"),
          ),
          TextField(
            controller: _password,
            obscureText: true,
            enableSuggestions: false,
            autocorrect: false,
            decoration: const InputDecoration(
              border: OutlineInputBorder(), hintText: "Password"),
          ),
          TextButton(
            onPressed: () async {
              final email = _email.text;
              final password = _password.text;
              await Firebase.initializeApp(
                options: DefaultFirebaseOptions.currentPlatform,
              );
              final userCredential = 
                await FirebaseAuth.instance.createUserWithEmailAndPassword(
                  email: email, password: password
                );
              print(userCredential);
            },
            child: const Text("Register"),
          )
        ])

I tried unrestricting my API keys from the Google Cloud Console, but that didn’t work. I’m using an IOS simulator. How can I solve this? Thanks in advance.

    Try to catch the error you get and print it! Then you probably get some more information. Maybe your input is incorrect.

    Try this:

    try {
  await FirebaseAuth.instance.signInWithEmailAndPassword(
    email: "[email protected]",
    password: "SuperSecretPassword!"
  );
} on FirebaseAuthException catch  (e) {
  print('Failed with error code: ${e.code}');
  print(e.message);
}

    do firebase intialization in the main function like this:

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