Reference Authentication Flow with Flutter & Firebase

This forked project has been upgraded to the latest packages.

YouTube video walk-throughs here:

This project shows how to implement a full authentication flow in Flutter, using various Firebase sign-in methods.

It aims to be a reference implementation. Think of it as "authentication done right".

Project goals

This project shows how to:

use the various Firebase sign-in methods
build a robust authentication flow
use appropriate state management techniques to separate UI, logic and Firebase authentication code
handle errors and present user-friendly error messages
write production-ready code following best practices

Feel free to use this in your own projects. 😉

NOTE: This project will be kept up to date with the latest packages and Flutter version.

Google Sign-in

Facebook Sign-in

Email & Password auth

Abstract AuthService class, modeled after the firebase_auth API
FirebaseAuthService implementation
MockAuthService for testing
Firebase project configuration for iOS & Android
Toggle FirebaseAuthService and MockAuthService at runtime via developer menu

To use this project with Firebase authentication, some configuration steps are required.

Create a new project with the Firebase console.
Add iOS and Android apps in the Firebase project settings.
On Android, use com.codingwithflutter.firebase_auth_demo_flutter as the package name (a SHA-1 certificate fingerprint is also needed for Google sign-in).
then, download and copy google-services.json into android/app.
On iOS, use com.codingwithflutter.firebaseAuthDemo as the bundle ID.
then, download and copy GoogleService-Info.plist into iOS/Runner, and add it to the Runner target in Xcode.
