| ## The Classic Counter, in MobX | ||
|
|
||
| The code below has an `observable` that tracks the count, increments using the | ||
| `increment` action and renders with an `Observer` widget (the `reaction`). | ||
|
|
||
| ```dart | ||
| import 'package:flutter/material.dart'; | ||
| import 'package:flutter_mobx/flutter_mobx.dart'; | ||
| import 'package:mobx/mobx.dart'; | ||
| class SimpleCounter { | ||
| final count = Observable(0); | ||
| void increment() { | ||
| runInAction(() => count.value++); | ||
| } | ||
| } | ||
| class CounterView extends StatefulWidget { | ||
| const CounterView({Key? key}) : super(key: key); | ||
| @override | ||
| CounterExampleState createState() => CounterExampleState(); | ||
| } | ||
| class CounterExampleState extends State<CounterView> { | ||
| final SimpleCounter counter = SimpleCounter(); | ||
| @override | ||
| Widget build(BuildContext context) => Scaffold( | ||
| appBar: AppBar( | ||
| backgroundColor: Colors.blue, | ||
| title: const Text('MobX Counter'), | ||
| ), | ||
| body: Center( | ||
| child: Column( | ||
| mainAxisAlignment: MainAxisAlignment.center, | ||
| children: <Widget>[ | ||
| const Text( | ||
| 'You have pushed the button this many times:', | ||
| ), | ||
| Observer( | ||
| builder: (_) => Text( | ||
| '${counter.count.value}', | ||
| style: const TextStyle(fontSize: 40), | ||
| )), | ||
| ], | ||
| ), | ||
| ), | ||
| floatingActionButton: FloatingActionButton( | ||
| onPressed: counter.increment, | ||
| tooltip: 'Increment', | ||
| child: const Icon(Icons.add), | ||
| ), | ||
| ); | ||
| } | ||
| ``` |
