Flutter CheckboxListTile – Example

Flutter CheckboxListTile Widget

Flutter CheckboxListTile widget displays a material design checkbox with a label.

Using CheckboxListTile class properties, we may change the colors, and also listen to the state changes.

Syntax

CheckboxListTile(
  title: const Text('Sample Label'),
  value: false,
  onChanged: () {},
),

Example

Flutter Application with a CheckboxListTile widget.

isChecked boolean variable is used to hold the state of this CheckboxListTile widget, whether checked (true) or not (false).

main.dart

import 'package:flutter/material.dart';

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

/// main application widget
class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  static const String _title = 'Flutter Application';

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: _title,
      home: Scaffold(
        appBar: AppBar(title: const Text(_title)),
        body: const MyStatefulWidget(),
      ),
    );
  }
}

/// stateful widget that the main application instantiates
class MyStatefulWidget extends StatefulWidget {
  const MyStatefulWidget({Key? key}) : super(key: key);

  @override
  State<MyStatefulWidget> createState() => _MyStatefulWidgetState();
}

/// private State class that goes with MyStatefulWidget
class _MyStatefulWidgetState extends State<MyStatefulWidget> {
  bool isChecked = false;
  @override
  Widget build(BuildContext context) {
    return Center(
      child: Column(
        children: <Widget>[
          const SizedBox(height: 30,),
          CheckboxListTile(
            title: const Text('Apple'),
            value: isChecked,
            onChanged: (bool? value) {
              setState(() {
                isChecked = value!;
              });
            },
          ),
        ],
      ),
    );
  }
}

Now, let us create a Flutter Application with multiple CheckboxListTile widgets.

main.dart

import 'package:flutter/material.dart';

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

/// main application widget
class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  static const String _title = 'Flutter Application';

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: _title,
      home: Scaffold(
        appBar: AppBar(title: const Text(_title)),
        body: const MyStatefulWidget(),
      ),
    );
  }
}

/// stateful widget that the main application instantiates
class MyStatefulWidget extends StatefulWidget {
  const MyStatefulWidget({Key? key}) : super(key: key);

  @override
  State<MyStatefulWidget> createState() => _MyStatefulWidgetState();
}

/// private State class that goes with MyStatefulWidget
class _MyStatefulWidgetState extends State<MyStatefulWidget> {
  bool isAppleChecked = false;
  bool isBananaChecked = false;
  bool isCherryChecked = false;
  @override
  Widget build(BuildContext context) {
    return Center(
      child: Column(
        children: <Widget>[
          CheckboxListTile(
            title: const Text('Apple'),
            value: isAppleChecked,
            onChanged: (bool? value) {
              setState(() {
                isAppleChecked = value!;
              });
            },
          ),
          CheckboxListTile(
            title: const Text('Banana'),
            value: isBananaChecked,
            onChanged: (bool? value) {
              setState(() {
                isBananaChecked = value!;
              });
            },
          ),
          CheckboxListTile(
            title: const Text('Cherry'),
            value: isCherryChecked,
            onChanged: (bool? value) {
              setState(() {
                isCherryChecked = value!;
              });
            },
          ),
        ],
      ),
    );
  }
}
