Flutter :如何将JSON的元素转换为list？

import 'dart:convert';

void main() {
  // 示例JSON字符串
  String jsonString = '''
    [
      {"name": "John", "age": 30},
      {"name": "Alice", "age": 25},
      {"name": "Bob", "age": 35}
    ]
  ''';

  // 将JSON字符串解析为Dart对象
  List<dynamic> jsonList = json.decode(jsonString);

  // 将解析后的JSON对象转换为列表
  List<Person> personList = jsonList.map((json) => Person.fromJson(json)).toList();

  // 打印输出每个人的姓名和年龄
  for (var person in personList) {
    print('${person.name}, ${person.age}');
  }
}

class Person {
  final String name;
  final int age;

  Person({required this.name, required this.age});

  // 从JSON中构造Person对象
  factory Person.fromJson(Map<String, dynamic> json) {
    return Person(
      name: json['name'],
      age: json['age'],
    );
  }
}
