如何在flutter中显示id匹配的列表

import 'package:flutter/material.dart';

class Item {
  final int id;
  final String name;

  Item({required this.id, required this.name});
}

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

class MyApp extends StatelessWidget {
  final List<Item> itemList = [
    Item(id: 1, name: 'Item 1'),
    Item(id: 2, name: 'Item 2'),
    Item(id: 3, name: 'Item 3'),
    Item(id: 4, name: 'Item 4'),
    Item(id: 5, name: 'Item 5'),
  ];

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Flutter List'),
        ),
        body: ListView.builder(
          itemCount: itemList.length,
          itemBuilder: (context, index) {
            final item = itemList[index];

            // 根据ID匹配筛选项目
            if (item.id == 3) {
              return ListTile(
                title: Text(item.name),
              );
            } else {
              return Container(); // 空容器，不显示其他项目
            }
          },
        ),
      ),
    );
  }
}
