如何使用Flutter中的“for loop”生成的小部件导航到另一个页面？

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: HomePage(),
      routes: {
        '/secondPage': (context) => SecondPage(),
      },
    );
  }
}

class HomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Home Page'),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            for (int i = 1; i <= 5; i++)
              ElevatedButton(
                onPressed: () {
                  Navigator.pushNamed(context, '/secondPage', arguments: i);
                },
                child: Text('Button $i'),
              ),
          ],
        ),
      ),
    );
  }
}

class SecondPage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    final int buttonNumber = ModalRoute.of(context).settings.arguments as int;

    return Scaffold(
      appBar: AppBar(
        title: Text('Second Page'),
      ),
      body: Center(
        child: Text('You pressed Button $buttonNumber'),
      ),
    );
  }
}
