Once these files are created, you will find a folder inside packages named auth_service:Įnable Authentication from Firebase Console and select Email/Password. When you run this command in the terminal, you will find that certain files were created: The above command will create a folder named auth_service inside packages. Then, in that location, run the following command: flutter create -template=package auth_service So, to create a package, we must first create a folder called packages inside our project. Packages in Flutter are libraries of code that can be shared among projects and are independent of the project that developers incorporate and reuse to make work easy and less time-consuming.Ĭreating a package for Firebase Auth is a very good option thereby reducing package dependencies on our main project. So, let's get started with the basic Email/Password Authentication! This article was created with an example run on Flutter 2.10 version!

Use the following command to generate SHA-1:įinal GoogleSignInAccount googleSignInAccount = await googleSignIn. If you want to clone and use this app, then you have to complete the following steps: Step 1: Generate the SHA-1 Combined with Local Authentication using Biometric ( local_auth).There are three versions of this project available: NOTE: The project is tested on Flutter 1.7 (stable) and using all the latest versions of the plugins.
