reactNative

React Native is a well-known mobile application development framework that allows developers to create rich, cross-platform mobile application UI using reusable components. It's ideal for building mobile applications and supports multi-platform reusable code, pre-built components, and a rich UI. Most well-known social media platforms, such as Facebook and Instagram, have been built using React Native. 

In this course, you’ll start with a brief introduction to React Native and then cover various built-in components of React Native categorized into different categories such as basic, user interface, user interaction, and list view components. Next, you’ll learn about concepts such as application styling, navigation, Hooks, state management, and database management. You’ll find interactive quizzes and challenges throughout the course to test your understanding.

By the end of this course, you’ll be able to develop mobile applications and kickstart your journey as a React Native developer.

Getting Started with Mobile App Development with React Native

The `Switch` component in React Native is a controlled component that renders boolean input and modifies its value accordingly. It changes its value based on user decisions. For example, `Switch` can be used to toggle dark mode inside an application on or off.

# Usage

To implement and use the `Switch` component, we first have to import it from the `react-native` library.

Once the `Switch` component has been imported, we can use it inside our application using the `<Switch/>` tag.

import React from 'react';
import { Switch } from 'react-native';

const App = () => {
  return (
    <Switch
      value={ false }
      disabled={ false }
    />
  );
}

export default App;

# Styling

The `Switch` component cannot be styled since it is just a controlled component that changes its value based on user decisions.

# Customizing

Several props can be used to customize the behavior of the `Switch` component. Let's briefly review some of these props.

## `value`

This prop can be used to specify the value of the `Switch`. It takes the value of type boolean. If the value is `true`, the state of the `Switch` will be changed to on. Otherwise, the state will be off. The default value of this prop is `false`.

## `disabled`

This prop is self-explanatory and can be used to disable the functionality of the `Switch`, i.e., the user will not be able to turn the `Switch` on or off.

## `thumbColor`

This prop can be used to set the color of the foreground `Switch` grip.

## `trackColor`

This prop can be used to give the `Switch` track a customized color.

The code snippet below shows how we can use props to customize the `Switch` component.
