如何将菜单动态添加到底部导航视图？

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  int _selectedIndex = 0;

  List<Map<String, dynamic>> _menuItems = [
    {
      'icon': Icons.home,
      'text': 'Home',
    },
    {
      'icon': Icons.search,
      'text': 'Search',
    },
    {
      'icon': Icons.person,
      'text': 'Profile',
    },
  ];

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Dynamic Bottom Navigation'),
      ),
      body: Center(
        child: Text('Page ${_selectedIndex + 1}'),
      ),
      bottomNavigationBar: BottomNavigationBar(
        currentIndex: _selectedIndex,
        onTap: (index) {
          setState(() {
            _selectedIndex = index;
          });
        },
        items: _menuItems.map((item) {
          return BottomNavigationBarItem(
            icon: Icon(item['icon']),
            label: item['text'],
          );
        }).toList(),
      ),
    );
  }
}
