![]() Log into Firebase using your Google account by running the following Step 1: Install the required command line tools If you don't already have a Flutter app, you can complete the GetĬreate a new Flutter app using your preferred editor or IDE. Operating system, including the following: Connect to the Cloud Functions emulator.Connect to the Cloud Storage for Firebase emulator.Connect to the Realtime Database emulator.To integrate Auth0 into your Flutter app, you need an Auth0 account. Set Up Auth0Īuth0 is an Identity-as-a-Service (IDaaS) platform that provides developers with features such as Social and Passwordless Login, among others, to ease online identity management. It displays a login button so that they can start the authentication process. This widget defines a view that your app shows to users who have not been authenticated yet by Auth0. dart file and replace its entire content with the following code template: /// - /// External Packages /// - import 'package:flutter/material.dart' /// - /// Profile Widget /// - /// - /// Login Widget /// - /// - /// App /// - void main ( ) = > runApp ( MyApp ( ) ) class MyApp extends StatefulWidget // □ New code The CLI tool generates a template project within a couple of seconds to get you started, which you can open in your preferred IDE. You'll find more details on this concept as you follow the article. auth0 parameter sets the hierarchy of your Flutter app, which is significant when you are implementing user authentication using a callback URL. To do this, open your terminal and navigate to your projects directory to run the following command: flutter create -org com.auth0 flutterdemo To facilitate the process of creating a new Flutter project, you will use the Flutter CLI tool. If you encounter any issues, the complete source code of the sample application is available on this GitHub repository. Try out the most powerful authentication platform for free. Your application will also have a profile screen where you can display detailed information about the logged-in user and a logout button. You won't have to build any forms, though! The application will leverage a login page provided by Auth0, the Universal Login page. Throughout this article, you'll build an application that allows users to log in or sign up using a social identity provider, such as Google, or a set of credentials, such as a username and password. You may have different options of open-source software libraries that can help you integrate your application with these two protocols - you don't have to start from scratch.įor your Flutter application using Auth0, you can delegate that integration job to Auth0 Flutter SDK, the official Auth0 library for Flutter applications. For mobile applications, OAuth 2.0 provides the Authorization Code Grant flow with PKCE, which is the recommended flow that you'll use throughout this tutorial.Ī significant benefit of using standards like OAuth 2.0 and OIDC is that you can decouple your application from a particular vendor. It provides different flows to address authentication requirements for various types of applications. OAuth 2.0 is not just for web applications. It expands the successful delegation model of OAuth 2.0 in many ways, like the ability to sign in, a JWT structured ID token, and discovery. OpenID Connect (OIDC) is an authentication protocol on top of OAuth 2.0. OAuth 2.0 allows users to give the third-party application access to resources, such as using their profile data on a social network platform, without needing to input their credentials on said application. You can see a typical example of OAuth 2.0 in action when a user tries to sign up for a third-party app using Google. It allows users to give third-party applications access to their resources. OAuth 2.0 is an industry-standard protocol for authorization. You will need an installation of the Dart and Flutter plugins, regardless of the IDE you decide to use. These IDEs integrate well with Flutter and make your development effective through the provision of tools to edit and refactor your Flutter application code. Flutter SDK: We tested this tutorial with SDK version 1.17.You also need to have the following installations on your machine: If you need help getting started, you can follow the codelabs on the Flutter website. Prerequisitesīefore getting started with this article, you need a working knowledge of Flutter. You can check out the code developed throughout the article in this GitHub repository. In this article, you will learn how to build and secure a Flutter application with Auth0 using the open-source Auth0 Flutter SDK library. Flutter is Google's cross-platform UI toolkit created to help developers build expressive and beautiful mobile applications.
