Presentation Transcript
Introduction to Cross-Platform Development Cross-platform development allows building apps for multiple platforms using a single codebase. Popular frameworks: Flutter & React Native. 2
Flutter Overview Created by Google Uses Dart language Widget-based UI framework High performance with Skia rendering engine Hot reload feature 3
React Native Overview Created by Facebook (Meta) Uses JavaScript & React Bridges native components Large community support Hot reload for faster development 4
Advantages of Cross-Platform Development Code reusability (Write once, run anywhere) Faster development & reduced costs Single development team required Consistent UI/UX across platforms Hot reload speeds up debugging 5
Challenges of Cross-Platform Development Performance may not match native apps Limited access to platform-specific features UI inconsistencies due to different OS behaviors Dependency on third-party libraries 6
Cross-Platform vs. Native Development Performance: Native is faster, Cross-platform is optimized Development Time: Cross-platform is faster UI/UX: Native has better OS consistency Cost: Cross-platform is more cost-effective 7
Best Practices for Cross-Platform Apps Use platform-agnostic UI elements Optimize for performance Use native modules when necessary Follow platform-specific design guidelines 8
Flutter: Simple UI Example import "package:flutter/material.dart"; void main() { runApp(MyApp()); } class MyApp extends StatelessWidget { @override Widget build(BuildContext context) { return MaterialApp( home: Scaffold( appBar: AppBar(title: Text("Hello Flutter")), body: Center(child: Text("Welcome!")), ), ); } } 9
React Native: Simple UI Example import React from "react"; import { Text, View } from "react-native"; export default function App() { return ( <View style={{ flex: 1, justifyContent: "center", alignItems: "center" }}> <Text>Hello React Native!</Text> </View> ); } 10
UI Comparison: Flutter vs. React Native Flutter: Custom widgets with high consistency React Native: Uses native components for a more native feel Customization: Flutter allows more control, React Native is more adaptive 11
Performance Considerations Flutter: Uses Skia for rendering, close to native speed React Native: Uses JavaScript bridge, may introduce performance overhead Optimization techniques: Avoid unnecessary re-renders, use native modules 12
When to Choose Flutter or React Native? Choose Flutter if you need high performance, custom UI, or target web & desktop Choose React Native if you prefer JavaScript, need a large community, or better native integrations 13
Future of Cross-Platform Development Improvements in performance and native integration Growth of frameworks like Flutter and React Native Expansion into web and desktop applications 14
Conclusion Cross-platform development offers efficiency and cost savings Flutter and React Native are leading frameworks Choosing the right framework depends on project requirements The future is bright with better optimizations and tooling 15
