如何在Flutter中使用Navigator.pages从堆栈中删除页面

import 'package:flutter/material.dart';

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

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

class HomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Home'),
      ),
      body: Center(
        child: RaisedButton(
          child: Text('Open Page 2'),
          onPressed: () {
            Navigator.of(context).pushAndRemoveUntil(
              MaterialPageRoute(builder: (context) => Page2()),
              (route) => false,
            );
          },
        ),
      ),
    );
  }
}

class Page2 extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Page 2'),
      ),
      body: Center(
        child: RaisedButton(
          child: Text('Remove Page 2'),
          onPressed: () {
            Navigator.of(context).pages.removeLast();
          },
        ),
      ),
    );
  }
}
