Generate Authentication Widgets

Execute the following command in your project's root folder in order to generate authentication widgets based on your Amplify configuration:

flutter packages pub run flutter_amplify_auth_ui:main

Options:

• --amplifyDir=path/to/amplify/folder :

  Path to Amplify configuration (usually the amplify folder) in your project root (defaults to ./amplify/).

• --targetDir=path/to/target/folder :

  Generated Flutter widgets will be generated within the specified folder (defaults to ./lib/generated_auth_classes/).

Full example with options:

flutter packages pub run flutter_amplify_auth_ui:main --amplifyDir=./amplify/ --targetDir=./lib/generated_auth_classes/

Use Generated Widgets

Easily integrate the generated authentication widgets in your project, e.g.:

import 'package:amplify_auth_cognito/amplify_auth_cognito.dart';
import 'package:amplify_flutter/amplify.dart';
import 'package:flutter/material.dart';

import 'generated_auth_classes/sign_in/sign_in_page.dart'; // <-- Import the generated widget

import 'amplifyconfiguration.dart';

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {

  @override
  initState() {
    super.initState();
    _configureAmplify();
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Amplify Auth UI Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      debugShowCheckedModeBanner: false,
      home: SignInPage( // <-- Include the generated widget in your widget tree
        onSignIn: (context) {
          //TODO Define what to do after sign in
        },
      ),
    );
  }

  void _configureAmplify() async {
    if (!mounted) return;

    Amplify.addPlugins([
      AmplifyAuthCognito(),
    ]);

    try {
      await Amplify.configure(amplifyconfig);
    } on AmplifyAlreadyConfiguredException {
      print("Tried to reconfigure Amplify; this can occur when your app restarts on Android.");
    }
  }
}
