flutter-auth-ui (faui)

faui is an authentication UI for Flutter. It registers users with email and password using Firebase security as a service ( SECaaS ). The library provides UI to register user, validate email, sign in, sign out and restore password. Supports silent sign in and access to Firestore.

Usage

Create Project in Firebase

If you want to test the library, use the demo project:

apiKey: "AIzaSyA3hshWKqeogfYiklVCCtDaWJW8TfgWgB4"

To create your own Firebase project:

Sign in to firebase console https://console.firebase.google.com/
Add, configure and open project
In the project open tab "Authentication" and then tab "Sign-in Method"
Click "Email/Password", set "Enable" and click "Save"
Select "Project Settings" (gear icon)
Copy your "Web API Key"

Set Dependency

Update pubspec.yaml to make sure your project references necessary packages:

dependencies:
  ...
  faui: <latest version>

Check <latest version> here.

Update Code

In the beginning of the method build of the widget that requires authentication (it should be stateful), add the code:

if (fauiUser == null) {
  return fauiBuildAuthScreen(
    onExit: this.setState((){...}),
    firebaseApiKey: "...",
  );
}

Import you need:

import 'package:faui/faui.dart';

Get user email:

fauiUser.email

Sign out:

fauiSignOut()

Silent sign-in:


// Before runApp:
WidgetsFlutterBinding.ensureInitialized();
await fauiTrySignInSilently(firebaseApiKey: '...');
...

// After sign in with dialog:
fauiSaveUserLocallyForSilentSignIn();

Custom Layout and Language

To customize UI and/or language, invoke fauiBuildCustomAuthScreen instead of fauiBuildAuthScreen.

See the demo for the details.

Use the Retrieved Token to Access Your Data to Firestore
