Implement email and password authentication in your app by inserting ONE widget from this package in your widget tree.
It is based on Firebase Authentication and Bloc.

Features

• Register user accounts using email and password authentication.
• Send and resend verification emails to confirm email addresses.
• Sign in users with email and password.
• Sign out users.
• Handle password reset scenarios.

Usage

1. Add Firebase to your Flutter app.
2. Install the firebase_auth plugin.
3. Install the flutter_bloc package.
4. Install this package!
5. Pass your widget to the AuthScreen constructor as a descendat of a widget that can provide a AuthBloc instance, like BlocBrovider<AuthBloc>.

import 'package:firebase_auth/firebase_auth.dart';
import 'package:flutter/material.dart';
import 'package:flutter_bloc/flutter_bloc.dart';
import 'package:nonso/nonso.dart' as nonso;

class MyApp extends StatelessWidget {
  final FirebaseAuth firebaseAuthInstance;
  const MyApp(this.firebaseAuthInstance, {super.key});

  @override
  Widget build(BuildContext context) {
    return BlocProvider<nonso.AuthBloc>(
      create: (context) => nonso.AuthBloc(firebaseAuthInstance),
      child: MaterialApp(
        title: 'Flutter Demo',
        localizationsDelegates: [nonso.AppLocalizations.delegate],
        supportedLocales: nonso.AppLocalizations.supportedLocales,
        home: nonso.AuthScreen(
          // This is your home screen
          const YourHomePage(title: 'Flutter Demo Home Page'),
        ),
      ),
    );
  }
}

6. Use context.read<AuthBloc>().state.user! to get information about the signed in user.

  import 'package:firebase_auth/firebase_auth.dart';

  Widget build(BuildContext context) {
    final User currentSignedInUser = context.read<AuthBloc>().state.user!;
    return Text("${currentSignedInUser.uid}");
  }

Here's an example of a Flutter app that uses this package to handle email and password authentication here. Make sure to use the correct values of your Firebase project in the firebase_options.dart file.
