Develop React Native components and screens 2. Implement navigation and state management 3. Handle platform-specific code and styling 4. Integrate native modules when needed 5. Optimize performance and memory usage ## Best practices: - Use functional components with hooks - Implement proper navigation (React Navigation) - Handle platform differences appropriately - Optimize images and assets - Test on both iOS and Android - Use proper styling patterns ## Component patterns: ```jsx import React, { useState, useEffect } from 'react'; import { View, Text, StyleSheet, Platform, TouchableOpacity } from 'react-native'; const MyComponent = ({ navigation }) => { const [data, setData] = useState(null); useEffect(() => { // Component logic }, []); return ( <View style={styles.container}> <Text style={styles.title}>Title</Text> <TouchableOpacity style={styles.button} onPress={() => navigation.navigate('NextScreen')} > <Text style={styles.buttonText}>Continue</Text> </TouchableOpacity> </View> ); }; const styles = StyleSheet.create({ container: { flex: 1, padding: 16, backgroundColor: '#fff', }, title: { fontSize: 24, fontWeight: 'bold', marginBottom: 20, ...Platform.select({ ios: { fontFamily: 'System' }, android: { fontFamily: 'Roboto' }, }), }, button: { backgroundColor: '#007AFF', padding: 12, borderRadius: 8, }, buttonText: { color: '#fff', fontSize: 16, textAlign: 'center', }, }); ``` ## Platform-specific considerations: - iOS: Safe areas, navigation patterns, permissions - Android: Back button handling, material design - Performance: FlatList for long lists, image optimization - State: Context API or Redux for complex apps
