Tag: Checkbox

Users can choose several alternatives from a list of possibilities by using checkboxes, which are a key component of user interfaces. We will look at creating checkboxes in Flutter and managing state changes in this blog article. All other widgets, including containers, list views, and others, can use checkboxes.

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

Checkbox Demo

Checkbox(  
  value: this.showvalue,   
  onChanged: (bool value) {  
    setState(() {  
      this.showvalue = value;   
    });  
  },
),

Creating a Checkbox

In Flutter, we can utilise the Checkbox widget to construct a checkbox. Let’s begin by configuring a straightforward Flutter application and making a checkbox:

import 'package:flutter/material.dart';

class CheckboxExample extends StatefulWidget {
  @override
  _CheckboxExampleState createState() => _CheckboxExampleState();
}

class _CheckboxExampleState extends State<checkboxexample> {
  bool _isChecked = false;

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Checkbox Example'),
      ),
      body: Center(
        child: Checkbox(
          value: _isChecked,
          onChanged: (bool newValue) {
            setState(() {
              _isChecked = newValue;
            });
          },
        ),
      ),
    );
  }
}

Checkboxes are essential elements for enabling users.
