What is Flutter and why is it popular for mobile app development?
Flutter is an open-source UI software development toolkit created by Google. It is widely popular for building natively compiled applications for mobile, web, and desktop from a single codebase.
To understand its popularity, consider the following key features:
- Single Codebase: Write once, run anywhere. This reduces development time and effort.
- Hot Reload: Developers can see changes in real-time without restarting the application, improving workflow.
- Rich Widgets: Flutter offers a wide range of customizable widgets that adhere to Material Design and Cupertino styles.
For example, to create a simple Flutter application, use the following code snippet:
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('Hello Flutter!')),
body: Center(child: Text('Welcome to Flutter!')),
),
);
}
}
