Can you explain how Flutter works for creating mobile applications?

Flutter is a framework from Google for creating cross-platform mobile applications using the Dart language. Its operation is based on the following:

• Flutter uses its own rendering engine, which draws the interface directly on the screen, bypassing native platform components.
• Dart code is compiled into native machine code (AOT compilation), ensuring high performance.
• The UI is built from widgets that can be combined and customized.
• Thanks to hot reload, developers can quickly see changes in the interface without restarting the entire application.

Example of a simple Flutter application:

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('Flutter Example')),
        body: Center(child: Text('Hello, Flutter!')),
      ),
    );
  }
}
