有没有办法更新BottomNavigationBarItems？

import 'package:flutter/material.dart';

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

class _MyHomePageState extends State<MyHomePage> {
  int _currentIndex = 0;
  List<BottomNavigationBarItem> _bottomNavBarItems = [
    BottomNavigationBarItem(
      icon: Icon(Icons.home),
      label: 'Home',
    ),
    BottomNavigationBarItem(
      icon: Icon(Icons.search),
      label: 'Search',
    ),
    BottomNavigationBarItem(
      icon: Icon(Icons.person),
      label: 'Profile',
    ),
  ];

  void _updateBottomNavBarItems() {
    setState(() {
      _bottomNavBarItems[0] = BottomNavigationBarItem(
        icon: Icon(Icons.home),
        label: 'New Home',
      );
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Bottom Navigation Bar Example'),
      ),
      body: Center(
        child: Text('Current Index: $_currentIndex'),
      ),
      bottomNavigationBar: BottomNavigationBar(
        currentIndex: _currentIndex,
        items: _bottomNavBarItems,
        onTap: (index) {
          setState(() {
            _currentIndex = index;
          });
        },
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: _updateBottomNavBarItems,
        child: Icon(Icons.update),
      ),
    );
  }
}
