Native Development (Swift/Kotlin)

Pros

• ✅ Best performance possible
• ✅ Full platform API access (day 1)
• ✅ Platform-specific UX feels natural
• ✅ Largest talent pool
• ✅ Best tooling (Xcode, Android Studio)

• ✅ Widget catalog is comprehensive

Cons

• ❌ Larger app size (4-8 MB overhead)
• ❌ Dart has smaller community than JS
• ❌ Some platform features require custom plugins
• ❌ Fewer developers in job market
• ❌ Web/Desktop support still maturing

When to Choose Flutter

✓ Need beautiful, custom UI
✓ Performance is important

✓ Team comfortable learning Dart
✓ Building for multiple platforms (mobile + web + desktop)
✓ Startup or mid-sized product

Examples:
- Google Ads
- Alibaba

Code Example (Flutter)

// Flutter - Counter App
import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: CounterScreen(),
    );
  }
}

class CounterScreen extends StatefulWidget {
  @override
  _CounterScreenState createState() => _CounterScreenState();
}

class _CounterScreenState extends State {
  int _counter = 0;

  void _incrementCounter() {
    setState(() {
      _counter++;
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: Text('Flutter Counter')),
      body: Center(
        child: Text(
          'Count: $_counter',
          style: TextStyle(fontSize: 24),
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: _incrementCounter,
        child: Icon(Icons.add),
      ),
    );
  }
}

Cons

• ❌ Performance can be an issue (JavaScript bridge)
• ❌ Relies on native modules for many features
• ❌ Breaking changes between versions
• ❌ Complex animations can be choppy
• ❌ Debugging can be challenging
• ❌ Native code knowledge often needed

When to Choose React Native

✓ Team knows React/JavaScript
✓ Need to ship fast (MVP/startup)

Code Example (React Native)

// React Native - Counter App
import React, { useState } from 'react';
import { View, Text, Button, StyleSheet } from 'react-native';

export default function App() {
  const [counter, setCounter] = useState(0);

  return (
    
      Count: {counter}
       setCounter(counter + 1)}
      />
    
  );
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
  },
  text: {
    fontSize: 24,
    marginBottom: 20,
  },
});
