Architecture Deep Dive

Flutter's Architecture

Flutter uses its own rendering engine built with C++, which draws UI components directly on a canvas provided by the platform. This approach gives Flutter complete control over every pixel on the screen.

Skia Graphics Engine: Powers Flutter's rendering pipeline
Platform Channels: Communicate with native platform APIs
Widget Tree: Declarative UI construction
Hot Reload: Instant code changes without losing state

React Native's Architecture

React Native has undergone significant architectural improvements with the introduction of the New Architecture (Fabric and TurboModules), making it more performant and reliable.

JavaScript Interface: JSI enables direct communication with native modules
Fabric Renderer: New rendering system with improved performance
TurboModules: Lazy-loading native modules for faster startup
Hermes Engine: Optimized JavaScript engine for React Native

Code Comparison: Building a Simple Counter App

Let's compare the code structure and syntax by building a simple counter application in both frameworks:

                    Flutter (Dart)
                    
import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Counter App',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      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: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            Text(
              'You have pushed the button:',
              style: TextStyle(fontSize: 16),
            ),
            Text(
              '$_counter times',
              style: TextStyle(fontSize: 24, fontWeight: FontWeight.bold),
            ),
          ],
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: _incrementCounter,
        child: Icon(Icons.add),
      ),
    );
  }
}
                    
                

                    React Native (JSX)
                    
import React, { useState } from 'react';
import {
  SafeAreaView,
  StyleSheet,
  Text,
  TouchableOpacity,
  View,
} from 'react-native';

const App = () => {
  const [counter, setCounter] = useState(0);

  const incrementCounter = () => {
    setCounter(counter + 1);
  };

  return (
    
      
        React Native Counter
      
      
      
        You have pushed the button:
        {counter} times
      
      
      
        +
      
    
  );
};

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: '#fff',
  },
  header: {
    backgroundColor: '#2196F3',
    padding: 20,
  },
  headerText: {
    color: '#fff',
    fontSize: 20,
    fontWeight: 'bold',
    textAlign: 'center',
  },
  content: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
  },
  label: {
    fontSize: 16,
  },
  counter: {
    fontSize: 24,
    fontWeight: 'bold',
    marginTop: 10,
  },
  button: {
    position: 'absolute',
    bottom: 30,
    right: 30,
    width: 60,
    height: 60,
    borderRadius: 30,
    backgroundColor: '#2196F3',
    justifyContent: 'center',
    alignItems: 'center',
  },
  buttonText: {
    color: '#fff',
    fontSize: 30,
  },
});

export default App;
