Flutter vs. React Native: The Ultimate Developer’s Guide for 2025

In 2025, mobile applications develop rapidly, while Flutter and Reacts Native is the best choice for development across platforms. But with a low-code rise and ai-head-out code generation platforms such as FAB Builder, development becomes faster, smarter and more efficient.

This Guide will Help You:

• Compare: Flutter and React Native in performance, ecosystem and developer experience
• Learn: Practical coding examples of both frames
• See: How FAB Builder automates and accelerates development of your application

What are Flutter and React Native?

Step 2: Flutter Setting Manually

If you prefer Manual Settings, follow these steps:

Install Flutter (Skip if installed)

flutter doctor

Ensure all addictions (Android Studio, SDK) are installed.

Create a new Flutter Project

flutter create my_flutter_app
cd my_flutter_app
flutter run

Your app Flutter is running!

Step 3: Build a Simple User Interface in Flutter

Replace the Main.dart file by this:

import 'package:flutter/material.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter vs React Native',
      theme: ThemeData(primarySwatch: Colors.blue),
      home: HomePage(),
    );
  }
}

class HomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: Text('Flutter vs React Native')),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            Text('Built with Flutter!', style: TextStyle(fontSize: 24)),
            SizedBox(height: 20),
            ElevatedButton(
              onPressed: () => print('FAB Builder Integration Coming Soon!'),
              child: Text('Click Me!'),
            ),
          ],
        ),
      ),
    );
  }
}

Run the Flutter application

flutter run

Your Flutter app is now alive!

How to create a native React app in 2025

Step 1: Create a native React app using FAB Builder

1. Open FAB Builder and Select React Native
2. Select Template (eg e-commerce, chat, dating panel)
3. Click generate code to get React Native Project
4. Download and open it to vs code

FAB Builder eliminates the code and speeds up the development of the user interface!

Step 2: Setting Manually Native

If you prefer Manual Settings, follow these steps:

Install React Native CLI (Skip if installed)

bash
NPM Installation -g React-Native-Cli

Create a new React Native project

bash
NPX React-NATIVE INIT MYREACTAPP
CD MyReactapp
NPX React-Native Start

Your native React application is set!

Step 3: Create a simple user interface in React Native

Replace app.js This:

Javascript
Import React from 'React';
import {View, text, button, styheet} z 'react-nantive';

Const app = () => {
  Return (

       built with native sinner!  console.log ("Fab Bubilder Integration soon!")} />

  );
};

Const Styles = Stylesheet.create ({
  container: {
    Flex: 1,
    JustifyContent: 'Center',
    Alignitys: 'Center',
    BackgroundColor: '#F5F5F5',
  },
  Text: {
    Fontsze: 24,
    Marginbottom: 20,
  },
});

Export default applications;

Start your native React App

bash
NPX React-Native Run-Android # for Android  
NPX React-Native Run-Ios # for iOS  

Your React Native App is now live!
