Flutter and React Native are both popular frameworks for building mobile applications. Both have their own set of pros and cons and choosing the best one for your next project can be a tough decision. In this blog, we will compare Flutter and React Native and help you determine which one is the best choice for your next mobile project.
So what’s Flutter?
Flutter is a relatively new framework for mobile development, but it has gained popularity in recent years. It is an open-source framework developed by Google and is based on the Dart programming language. Flutter uses a reactive programming model, which makes it easy to build high-performance, responsive, and animated user interfaces. The framework also provides a rich set of customizable widgets that can be used to create beautiful and unique designs.
and what’s React Native?
React Native, on the other hand, is an open-source framework developed by Facebook and is based on JavaScript. It uses a similar approach to building user interfaces as React, which is a popular JavaScript library for building web applications. React Native allows developers to build mobile apps that look and feel like native apps, but with the flexibility and power of JavaScript.
App Performance Comparison
When it comes to performance, Flutter has an edge over React Native. The reactive programming model used by Flutter makes it easier to create high-performance apps that run smoothly on both iOS and Android. React Native, on the other hand, relies on the JavaScript bridge to communicate with native components, which can sometimes lead to performance issues.
Faster Development Time in Flutter
Another advantage of Flutter is its fast development time. The framework’s hot reload feature allows developers to see the changes they make to the code instantly, without having to rebuild the entire app. This feature can save a lot of time and make the development process more efficient.
React Native has a wider range of Third Party Library
React Native, on the other hand, has a larger community and a wider range of third-party libraries and modules available. This means that developers can find solutions to common problems more easily and can also take advantage of pre-built components to speed up their development process.
Which framework provides a smaller App size?
In terms of app size, React Native tends to have a larger app size compared to Flutter. React Native uses JavaScript which requires a JavaScript engine to be bundled with the app, which increases the app size. On the other hand, Flutter does not have this issue as it uses Dart, a programming language that does not require a separate engine to be bundled.
Create a Simple Button in Flutter and React Native
First, here’s an example of how to create a simple button in Flutter:
import 'package:flutter/material.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
body: Center(
child: RaisedButton(
onPressed: () {
print('Button pressed');
},
child: Text('Press me'),
),
),
),
);
}
}
In this example, we import the material.dart package, which provides a set of pre-built widgets that are styled according to the Material Design guidelines. We create a StatelessWidget called MyApp, which is the root widget of our app. In this build method, we use the Scaffold widget to create a basic layout, and inside it, we use a Center widget to centre our button. The RaisedButton widget is one of the pre-built widgets that are provided by the material.dart package. It's a button that raises when pressed, and we can customize its appearance and behaviour by passing various arguments to the constructor.
Now, let’s see how to create the same button in React Native:
import React, { useState } from 'react';
import { StyleSheet, Text, View, TouchableOpacity } from 'react-native';
export default function App() {
const [buttonText, setButtonText] = useState('Press me');
return (
<View style={styles.container}>
<TouchableOpacity
style={styles.button}
onPress={() => {
console.log('Button pressed');
setButtonText('Pressed');
}}>
<Text style={styles.buttonText}>{buttonText}</Text>
</TouchableOpacity>
</View>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
},
button: {
backgroundColor: '#4CAF50',
padding: 10,
borderRadius: 5,
},
buttonText: {
fontSize: 20,
color: 'white',
},
});
In this example, we import the react and react-native packages, which provide the basic building blocks for creating React Native apps. We create a functional component called App, which returns a JSX element that represents the layout of our app. We use the View and Text components to create a container and a label for our button, respectively. The TouchableOpacity component is a special component provided by React Native that can be used to create buttons that respond to touch events. We can customize the appearance and behaviour of our button by passing various styles to the components using the StyleSheet module.
As you can see, both frameworks use a similar approach to creating user interfaces, but the syntax and the specific widgets and components used are different. Flutter’s widgets are built using the Dart programming language, whereas React Native’s components are built using JavaScript.
What in terms of the Job Market?
In terms of the job market, both frameworks are widely used, and there is a high demand for developers who are proficient in either framework. According to a recent survey by StackOverflow, both Flutter and React Native are among the top 10 most loved frameworks, libraries and technologies among developers.
Conclusion
In conclusion, both Flutter and React Native are great frameworks for building mobile applications. Flutter is a newer framework that is gaining popularity due to its fast development time, high performance, and beautiful widgets. React Native, on the other hand, is a more established framework that has a larger community and a wider range of third-party libraries available. The best choice for your next mobile project will depend on your specific needs and requirements.
Both Flutter and React Native have their own set of pros and cons, and the best choice for your next mobile project will depend on your specific needs and requirements. Consider factors such as performance, development time, and community support when making your decision.
