smf_firebase_auth 0.5.0

The SMF module of Firebase Authentication for the Flutter app that SMF generates. The users of the app sign in with an email address and a password, or as anonymous users.

smf_firebase_auth

The SMF module of Firebase Authentication with firebase_auth. It provides the auth role of SMF: the users of the app sign in with an email address and a password, and the app can sign in anonymous users.

The auth role generates appSession, which tells who uses the app and through which the code of the app signs in, up and out, and the AuthService interface. This module adds firebase_auth to the app and implements the interface on FirebaseAuth. Firebase keeps the user on the device, so the app knows who is signed in before its first frame. The service gives each error code of Firebase a reason that the app shows a text for. When sign-in is not enabled in the Firebase project, the failure has a hint for the developer that tells how to enable it.

Firebase Authentication works on the Firebase app, so the module depends on smf_firebase_core, which comes with it and sets up Firebase.

The ways to sign in are enabled in the Firebase project, not in the code: Email/Password, and Anonymous for an app that signs in anonymous users. The module generates tool/enable_firebase_sign_in.dart, a script of the app that enables them with the Firebase CLI 15.6.0 or later. In a terminal, smf create offers to run it right after flutterfire configure configured the app. It asks first, because the Firebase CLI adds a web app to a project that has none, which the Firebase console does not. The README of the app describes both ways.

Use with the SMF CLI

smf create asks which module provides the authentication of the app, and offers none as well. To choose this one without the question:

smf create my_app -m firebase_auth

--auth-mode says who may use the app without an account: required, the default, guest or anonymous.

You don't add this package to an app yourself: smf create of the SMF CLI puts what the module generates into the app.

SMF generates apps for Flutter 3.44 or newer and Dart 3.12 or newer. It is tested on macOS, Linux and Windows.
