Flutter Firebase, Error = Ignoring Header X-Firebase-Locale because its value was null

Question

I am trying to add Firebase Authentication to my app via email and password signup and login. When I test it out, it does not navigate to the next screen and I get the following message:

"W/System ( 9510): Ignoring header X-Firebase-Locale because its value was null."

Here is my main.dart:

Here is my main.dart:

import 'package:firebase_core/firebase_core.dart';
import 'package:firebaseback/Login.dart';
import 'package:flutter/material.dart';

void main() async{

WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp();

  runApp(const MyApp());
}

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

  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Firebase backend',
      theme: ThemeData(

        primarySwatch: Colors.blue,
      ),
      home: const Login(),
