Mobile App Development (React Native)

Build cross-platform mobile applications for iOS and Android using React Native. This tutorial will teach you how to set up your development environment, create UI components, manage state, and integrate with native device features. You'll learn to write code once and deploy it everywhere.

Key topics include:

• React Native CLI and Expo
• Components, Props, and State
• Navigation with React Navigation
• Accessing native device features

Basic React Native Component

A fundamental building block of any React Native app is a component. Components are small, reusable pieces of UI. Here's a simple "Hello World" component:

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

const HelloWorldApp = () => {
  return (
    <View style={styles.container}>
      <Text style={styles.text}>Hello, World!</Text>
    </View>
  );
};

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#F5FCFF',
  },
  text: {
    fontSize: 20,
    textAlign: 'center',
    margin: 10,
  },
});

export default HelloWorldApp;

Setting up a New Project (Expo CLI)

Expo CLI is a tool that helps you create and manage React Native projects. It provides a quick way to get started without configuring native build tools.

npm install -g expo-cli
expo init MyAwesomeApp
cd MyAwesomeApp
npm start
