MattCorp Login (for Flutter)

MattCorp Id authentication for Flutter projects.


This package is a work-in-progress library to allow Flutter projects to easily use MattCorp Id for secure authentication. It is not recommended for use at this time.


  1. Import the package
  2. Create a new MattCorpLogin instance, passing in the correct client named parameter
  3. Call the asynchronous login method on the MattCorpLogin instance
  4. This will return a JWT (or an error) as a string
  5. Consume this JWT as normal (e.g. the same as your web implementation)

0.1.1 - 20th April 2018

  • No noticeable differences to end-users
  • Reworked internals to use Completer
  • Moved most logic to LoginScreen

0.1.0 - 18th April 2018

  • Breaking change - client parameter now required during initialization

0.0.2 - 18th April 2018

  • Added basic example application

0.0.1 - 18th April 2018

  • Initial release
  • Basic async login support
  • Not for production use - await version 1.0.0

void main() => runApp(new MyApp());

  Widget build(BuildContext context) {
    return new MaterialApp(
      title: 'Flutter Demo',
      theme: new ThemeData(
        // This is the theme of your application.
        // Try running your application with "flutter run". You'll see the
        // application has a blue toolbar. Then, without quitting the app, try
        // changing the primarySwatch below to and then invoke
        // "hot reload" (press "r" in the console where you ran "flutter run",
        // or press Run > Flutter Hot Reload in IntelliJ). Notice that the
        // counter didn't reset back to zero; the application is not restarted.

class MyHomePage extends StatefulWidget {
  MyHomePage({Key key, this.title}) : super(key: key);

  // This widget is the home page of your application. It is stateful, meaning
  // that it has a State object (defined below) that contains fields that affect
  // how it looks.

  // This class is the configuration for the state. It holds the values (in this
  // case the title) provided by the parent (in this case the App widget) and
  // used by the build method of the State. Fields in a Widget subclass are
  // always marked "final".

  int _counter = 0;

  void _incrementCounter() {

      // This call to setState tells the Flutter framework that something has
      // changed in this State, which causes it to rerun the build method below
      // so that the display can reflect the updated values. If we changed
      // _counter without calling setState(), then the build method would not be
      // called again, and so nothing would appear to happen.

  Widget build(BuildContext context) {
    // This method is rerun every time setState is called, for instance as done
    // by the _incrementCounter method above.
    // The Flutter framework has been optimized to make rerunning build methods
    // fast, so that you can just rebuild anything that needs updating rather
    // than having to individually change instances of widgets.
    return new Scaffold(
      appBar: new AppBar(
        // Here we take the value from the MyHomePage object that was created by
        // the method, and use it to set our appbar title.

      body: new Center(
        // Center is a layout widget. It takes a single child and positions it
        // in the middle of the parent.
        child: new Column(
          // Column is also layout widget. It takes a list of children and
          // arranges them vertically. By default, it sizes itself to fit its
          // children horizontally, and tries to be as tall as its parent.
          // Invoke "debug paint" (press "p" in the console where you ran
          // "flutter run", or select "Toggle Debug Paint" from the Flutter tool
          // window in IntelliJ) to see the wireframe for each widget.
          // Column has various properties to control how it sizes itself and
          // how it positions its children. Here we use mainAxisAlignment to
          // center the children vertically; the main axis here is the vertical
          // axis because Columns are vertical (the cross axis would be
          // horizontal).
