Flutter vs React Native vs Native iOS/Android Development: A Detailed Comparison
In the world of mobile app development, the debate between using Flutter, React Native, or going with native iOS/Android development is a critical one for developers, businesses, and product managers. Each approach has its pros and cons, and understanding them is key to choosing the right technology for your mobile application.
This article delves deep into the strengths and weaknesses of Flutter and React Native while comparing them to native development on iOS and Android. By understanding the differences, you can make an informed decision for your next project.
1. Native iOS and Android Development
Native development refers to building apps specifically for one platform, either iOS using Swift/Objective-C or Androidusing Java/Kotlin. In this method, you use platform-specific tools and languages to build an application that is optimized for a specific operating system (OS).

Disadvantages of Native Development:
2. React Native
React Native, developed by Facebook, is a popular open-source framework that allows developers to build mobile apps using JavaScript and React. With React Native, you can write a single codebase that runs on both iOS and Android platforms.
Advantages of React Native:
Disadvantages of React Native:
3. Flutter
Flutter, developed by Google, is another cross-platform framework that allows developers to build mobile apps using the Dart programming language. What sets Flutter apart from React Native is that it uses a rendering engine to draw UI components from scratch rather than relying on native platform components.

Which One Should You Choose?
Creating the same UI in React Native, Flutter, iOS (Swift/Objective-C), and Android (Java/Kotlin) will follow similar principles but differ in the language and specific components used. Here's a sample code comparison for a basic UI that includes:
1. React Native
React Native uses JavaScript and React components to build the interface. Here's the UI:
import React from 'react';
import { View, Text, TextInput, Button, StyleSheet } from 'react-native';
export default function App() {
return (
<View style={styles.container}>
<Text style={styles.header}>Sample UI</Text>
<TextInput style={styles.input} placeholder="Enter text" />
<Button title="Submit" onPress={() => alert('Submitted!')} />
</View>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
padding: 20,
},
header: {
fontSize: 24,
marginBottom: 20,
},
input: {
borderWidth: 1,
padding: 10,
marginBottom: 20,
width: '100%',
},
});
2. Flutter
In Flutter, you use Dart and widgets for building the UI. Here’s the same UI:
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('Sample UI'),
),
body: Padding(
padding: const EdgeInsets.all(20.0),
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
TextField(
decoration: InputDecoration(
border: OutlineInputBorder(),
labelText: 'Enter text',
),
),
SizedBox(height: 20),
ElevatedButton(
onPressed: () {
print('Submitted!');
},
child: Text('Submit'),
),
],
),
),
),
);
}
}
3. iOS (Swift)
For native iOS development using Swift, here's the UI:
import UIKit
class ViewController: UIViewController {
let textField: UITextField = {
let tf = UITextField()
tf.placeholder = "Enter text"
tf.borderStyle = .roundedRect
return tf
}()
let button: UIButton = {
let btn = UIButton(type: .system)
btn.setTitle("Submit", for: .normal)
btn.addTarget(self, action: #selector(handleSubmit), for: .touchUpInside)
return btn
}()
override func viewDidLoad() {
super.viewDidLoad()
view.backgroundColor = .white
view.addSubview(textField)
view.addSubview(button)
textField.frame = CGRect(x: 20, y: 200, width: view.frame.width - 40, height: 40)
button.frame = CGRect(x: 20, y: 250, width: view.frame.width - 40, height: 50)
}
@objc func handleSubmit() {
print("Submitted!")
}
}
4. Android (Kotlin)
For native Android development with Kotlin, here's the UI layout and logic:
<LinearLayout xmlns:android="https://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:padding="20dp"
android:gravity="center">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Sample UI"
android:textSize="24sp"
android:layout_marginBottom="20dp"/>
<EditText
android:id="@+id/inputField"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Enter text"
android:layout_marginBottom="20dp"
android:padding="10dp"
android:background="@android:drawable/editbox_background"/>
<Button
android:id="@+id/submitButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Submit" />
</LinearLayout>
import android.os.Bundle
import android.widget.Button
import android.widget.EditText
import android.widget.Toast
import androidx.appcompat.app.AppCompatActivity
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val inputField = findViewById<EditText>(R.id.inputField)
val submitButton = findViewById<Button>(R.id.submitButton)
submitButton.setOnClickListener {
Toast.makeText(this, "Submitted!", Toast.LENGTH_SHORT).show()
}
}
}
Key Differences:
Each approach has its own strengths and is suited to different types of projects depending on factors like performance requirements, UI complexity, and team expertise.
Conclusion
The choice between Flutter, React Native, and native development depends largely on your project requirements, the complexity of your app, and your team's skillset. Native development offers the best performance and full access to platform APIs but comes at the cost of higher development time and maintenance. React Native and Flutter, on the other hand, provide faster development cycles and lower costs due to their cross-platform nature, with Flutter offering superior performance and UI consistency compared to React Native.
By carefully considering your needs—whether it’s rapid development, performance, or a rich user interface—you can select the right technology to drive your mobile application project to success.
