This section shows the way to configure all Sign In features: Google, Apple, SMS, Facebook, Email.

Most of these features require Firebase to be set.

You can do these steps to configure the new App when using any service for Firebase:

  1. Using the Firebase Console, add an Android app to your project: Follow the assistant, download the generated google-services.json file, and place it inside android/app.

  2. Using the Firebase Console, add an iOS app to your project: Follow the assistant, download the generated GoogleService-Info.plist file, open ios/Runner.xcworkspace with Xcode, and within Xcode place the file inside ios/Runner.

When installing, if you get issue, please go to Common Questions or Common Issues to find the solutions.

1. Google Sign In

2. Apple Sign In

FDK path

This is a rejected message from Appstore by recent policies update from Apple:

“We noticed that your app uses a third-party login service but does not offer Sign in with Apple. To resolve this issue, please revise your app to offer Sign in with Apple as an equivalent login option. To learn more, see the Sign in with Appl Overview.”. To resolve the message, the login form should include the Apple Sign-In.

3. SMS Sign In

3.1 Integrate with the SMS Login:

Please follow this guide to integrate with the SMS Login.

4. Facebook Sign In

This part shows the way to set up Facebook login on your Flutter application. This needs to use the FlutterFacebookLogin package

AndroidX support

Install flutterfacebooklogin package

  • Step 1: Add this command to dependencies in the pubspec.yaml file:
  flutter_facebook_login: ^3.0.0
  • Step 2: Run this command to install package:
$ flutter pub get
  • Step 3: Import it in your Dart code:
import 'package:flutter_facebook_login/flutter_facebook_login.dart';


  • Step 1: In the Facebook Login documentation for Android site, finish all steps in 2 parts: the "Associate Your Package Name and Default Class with Your App" and "Provide the Development and Release Key Hashes for Your App".
  • Step 2: Find your Facebook App ID in your Facebook App's dashboard in the Facebook developer console.
  • Step 3: Create file /android/app/src/main/res/values/strings.xml. If this file exists, just edit the content same with below:
<?xml version="1.0" encoding="utf-8"?>
    <string name="app_name">Your App Name here.</string>

    <!-- Replace "000000000000" with your Facebook App ID here. -->
    <string name="facebook_app_id">000000000000</string>

/// Option to show/hide the Social Login
const kLoginSetting = {
  "IsRequiredLogin": false,
  'showAppleLogin': true,
  'showFacebook': true,

"kIsResizeImage": false,

File lib/common/config/general.dart:

This feature is available for the WooCommerce only. To enable the native forgot password screen, we just only set forgetPassword: "" in the lib/common/config.dart file.

/// set blank to use as native screen
