可以在Flutter中使用ListView的搜索栏吗？

import 'package:flutter/material.dart';

class CustomSearchDelegate extends SearchDelegate {
  @override
  List<Widget> buildActions(BuildContext context) {
    return [
      IconButton(
        icon: Icon(Icons.clear),
        onPressed: () {
          query = '';
        },
      ),
    ];
  }

  @override
  Widget buildLeading(BuildContext context) {
    return IconButton(
      icon: Icon(Icons.arrow_back),
      onPressed: () {
        close(context, null);
      },
    );
  }

  @override
  Widget buildResults(BuildContext context) {
    // 根据搜索内容query展示搜索结果
    return ListView(
      children: [
        ListTile(
          title: Text('搜索结果1'),
        ),
        ListTile(
          title: Text('搜索结果2'),
        ),
      ],
    );
  }

  @override
  Widget buildSuggestions(BuildContext context) {
    // 根据搜索内容query展示搜索建议
    return ListView(
      children: [
        ListTile(
          title: Text('搜索建议1'),
        ),
        ListTile(
          title: Text('搜索建议2'),
        ),
      ],
    );
  }
}

class ListViewWithSearchBar extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('ListView with Search Bar'),
        actions: [
          IconButton(
            icon: Icon(Icons.search),
            onPressed: () {
              showSearch(
                context: context,
                delegate: CustomSearchDelegate(),
              );
            },
          ),
        ],
      ),
      body: ListView(
        children: [
          ListTile(
            title: Text('Item 1'),
          ),
          ListTile(
            title: Text('Item 2'),
          ),
          ListTile(
            title: Text('Item 3'),
          ),
        ],
      ),
    );
  }
}
