Flutter:如何在不实际导航的情况下更改以前的导航路线？

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      home: HomeScreen(),
    );
  }
}

class HomeScreen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Home Screen'),
      ),
      body: Center(
        child: ElevatedButton(
          onPressed: () {
            // 获取当前的NavigatorState
            final NavigatorState navigator = Navigator.of(context);
            // 更改当前的路由路径
            navigator.setNewRoutePath('/new-route');
          },
          child: Text('Change Route Without Navigating'),
        ),
      ),
    );
  }
}

class NewRoute extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('New Route'),
      ),
      body: Center(
        child: Text('This is the new route'),
      ),
    );
  }
}

void main() {
  runApp(MaterialApp(
    title: 'Flutter Demo',
    initialRoute: '/',
    routes: {
      '/': (context) => HomeScreen(),
      '/new-route': (context) => NewRoute(),
    },
  ));
}
