Flutter Checkbox

Flutter Checkbox Example

In Flutter, the Checkbox widget is commonly used to represent a binary choice (checked or unchecked). Here’s an example :

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

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key, required this.title});
  final String title;
  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {


  List<String> items = List.generate(5, (index) => 'Item ${index + 1}');
  List<bool> selectedItems = List.generate(5, (index) => false);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Flutter Checkbox Example'),
      ),
      body: ListView.builder(
        itemCount: items.length,
        itemBuilder: (context, index) {
          return ListTile(
            title: Text(items[index]),
            leading: Checkbox(
              value: selectedItems[index],
              onChanged: (value) {
                setState(() {
                  selectedItems[index] = value!;
                });
              },
            ),
          );
        },
      ),
    );
  }
