如何在flutter中从json对象中读取列表？

{
  "list": [
    {"id": 1, "name": "Item 1"},
    {"id": 2, "name": "Item 2"},
    {"id": 3, "name": "Item 3"}
  ]
}

class Item {
  final int id;
  final String name;

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

  factory Item.fromJson(Map<String, dynamic> json) {
    return Item(
      id: json['id'],
      name: json['name'],
    );
  }
}

var jsonList = json.decode(jsonString)['list'];

List<Item> itemList = jsonList.map((json) => Item.fromJson(json)).toList();

import 'dart:convert';

class Item {
  final int id;
  final String name;

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

  factory Item.fromJson(Map<String, dynamic> json) {
    return Item(
      id: json['id'],
      name: json['name'],
    );
  }
}

void main() {
  String jsonString = '''
  {
    "list": [
      {"id": 1, "name": "Item 1"},
      {"id": 2, "name": "Item 2"},
      {"id": 3, "name": "Item 3"}
    ]
  }
  ''';

  var jsonList = json.decode(jsonString)['list'];
  List<Item> itemList = jsonList.map((json) => Item.fromJson(json)).toList();

  // 打印每个Item对象的属性
  for (var item in itemList) {
    print('ID: ${item.id}, Name: ${item.name}');
  }
}
