Frontegg Flutter SDK

This packages enables the usage of core Frontegg features in mobile applications built with flutter. Using this package, you'll be able to integrate Frontegg's login and signup flows.

User management (administration box) capabilities are not available using the flutter SDk.

Getting started

In pubspec.yaml:

frontegg: ...version

Import in project

import 'package:frontegg_mobile/frontegg.dart';
final frontegg = Frontegg("baseUrl", "logoImage");
FronteggUser? user;



  child: Text('login'),
  onPressed: () async {
    user = await frontegg.login(context);
    setState(() {});

Sign Up

  child: Text('signup'),
  onPressed: () async {
    user = await frontegg.signup(context);
    setState(() {});

Log out

  child: Text('logout'),
  onPressed: () async {
  user = await frontegg.logout();
  setState(() {
    if (user?.isAuthorized == false) {
    user = null;

User Information

after login

    user?.email, user?.name, user?.phoneNumber

accessToken is saved in shared preferences, in order to get it, use:

import 'package:shared_preferences/shared_preferences.dart';

final SharedPreferences prefs = await SharedPreferences.getInstance();
final String? token = prefs.getString('accessToken');
final String? refreshToken = prefs.getString('refreshToken');


If you need localization (i18n), create a folder called localization in a root directory of the application and a json file that will contain the translations (e.g. filename.json. don't forget to add it in pubspec.yaml) and add it while initialization like:

final frontegg = Frontegg("baseUrl", "logoImage", localizationFileName: 'filename.json');
FronteggUser? user;
