Practical Code Example

To illustrate the practical application of state management concepts discussed in these resources, let’s explore a simple example using the Provider package in Flutter. This example demonstrates how to manage a counter state in a Flutter app.

import 'package:flutter/material.dart';
import 'package:provider/provider.dart';

// Define a ChangeNotifier to manage the counter state
class Counter with ChangeNotifier {
  int _count = 0;

  int get count => _count;

  void increment() {
    _count++;
    notifyListeners();
  }
}

void main() {
  runApp(
    ChangeNotifierProvider(
      create: (context) => Counter(),
      child: MyApp(),
    ),
  );
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: CounterScreen(),
    );
  }
}

class CounterScreen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Provider Counter Example'),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            Text(
              'You have pushed the button this many times:',
            ),
            Consumer<Counter>(
              builder: (context, counter, child) {
                return Text(
                  '${counter.count}',
                  style: Theme.of(context).textTheme.headline4,
                );
              },
            ),
          ],
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: () {
          Provider.of<Counter>(context, listen: false).increment();
        },
        tooltip: 'Increment',
        child: Icon(Icons.add),
      ),
    );
  }
}

Explanation:

• ChangeNotifier: The Counter class extends ChangeNotifier, which allows it to notify listeners when the state changes.
• Provider: The ChangeNotifierProvider widget is used to provide the Counter instance to the widget tree.
• Consumer: The Consumer widget listens for changes in the Counter and rebuilds the UI when the counter value changes.
