Master React Native CheckBox Custom Components

From: React Native Components , CheckBox Component Last Updated: 7 months ago

step-by-step breakdown of the provided React Native Custom CheckBox component:

1. Component Structure:
     The component is created using the `React` and `useState` from 'react' and basic UI elements like `View`, `Text`, and `TouchableOpacity` from 'react-native'.
     It maintains the state of the checkbox using the `useState` hook.

2. Properties:
       The component accepts several properties for customization:
      `label`: The text label displayed next to the checkbox.
      `enabled`: A boolean indicating whether the checkbox is enabled or disabled. Defaults to `true`.
      `borderColor`: The color of the checkbox border.
      `enabledBorderColor`: The color of the checkbox border when it's enabled.
      `onValueChange`: A callback function triggered when the checkbox value changes.

3. Event Handling:
     The `handlePress` function is invoked when the TouchableOpacity is pressed.
     It checks if the checkbox is enabled before updating its state and triggering the `onValueChange` callback.

4. Styling:
     The component is styled using the `StyleSheet.create` method.
     The checkbox container has a row layout, a border, and padding.
     The actual checkbox is a square with rounded corners, and its background color changes based on its state.

5. Usage:
    The component is then used in a parent component, where you can customize its appearance and behavior by passing the desired properties.
    An example usage is provided in a hypothetical app where the component is used to enable or disable a feature, and a callback logs the checkbox value.

6. Customization:
    Developers can easily customize the component by adjusting the styles or extending the properties based on their specific requirements.

7. Benefits:
   The component provides a simple and intuitive way to integrate customizable checkboxes into React Native applications.
   It enhances user interaction by allowing developers to control the checkbox's appearance and behavior.

8. Flexibility:
   Developers can integrate multiple instances of the Custom CheckBox component with different configurations based on their application's needs.

By following these steps, you can integrate this Custom CheckBox component into your React Native application, providing a flexible and user-friendly checkbox solution.


// App.js

import React from 'react';
import { View, StyleSheet } from 'react-native';
import CustomCheckBox from './CustomCheckBox'; // Adjust the import path based on your project structure

const App = () => {
  const handleCheckBoxChange = (value) => {
    console.log('CheckBox value:', value);

  return (
    <View style={styles.container}>
        label="Enable Feature"
      {/* Add more CustomCheckBox components with different configurations as needed */}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    padding: 20,

export default App;



You can use this component in your React Native application and pass the desired properties like label, enabled, borderColor, enabledBorderColor, and onValueChange to customize its behavior and appearance.


// CustomCheckBox.js

import React, { useState } from 'react';
import { View, Text, TouchableOpacity, StyleSheet } from 'react-native';

const CustomCheckBox = ({
  enabled = true,
  borderColor = '#000',
  enabledBorderColor = '#00f',
}) => {
  const [isChecked, setChecked] = useState(false);

  const handlePress = () => {
    if (enabled) {
      const newValue = !isChecked;
      onValueChange && onValueChange(newValue);

  return (
    <TouchableOpacity onPress={handlePress} activeOpacity={0.8} disabled={!enabled}>
      <View style={[styles.checkboxContainer, { borderColor: enabled ? enabledBorderColor : borderColor }]}>
        <View style={[styles.checkbox, { backgroundColor: isChecked ? enabledBorderColor : 'transparent' }]} />
        <Text style={styles.label}>{label}</Text>

const styles = StyleSheet.create({
  checkboxContainer: {
    flexDirection: 'row',
    alignItems: 'center',
    marginBottom: 10,
    borderWidth: 2,
    borderRadius: 5,
    padding: 5,
  checkbox: {
    width: 20,
    height: 20,
    borderRadius: 3,
    borderWidth: 2,
    marginRight: 5,
  label: {
    fontSize: 16,

export default CustomCheckBox;
