如果在Flutter/Dart中没有名称/键，如何序列化/解析嵌套的JSON数组

[
  {"name": "John", "age": 25},
  {"name": "Jane", "age": 30},
  {"name": "Bob", "age": 35}
]

class Person {
  String name;
  int age;

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

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

  Map<String, dynamic> toJson() {
    return {
      'name': name,
      'age': age,
    };
  }
}

String jsonString = '[{"name": "John", "age": 25}, {"name": "Jane", "age": 30}, {"name": "Bob", "age": 35}]';
List<dynamic> jsonList = jsonDecode(jsonString);
List<Person> persons = jsonList.map((json) => Person.fromJson(json)).toList();

List<Person> persons = [
  Person(name: "John", age: 25),
  Person(name: "Jane", age: 30),
  Person(name: "Bob", age: 35),
];
String jsonString = jsonEncode(persons.map((person) => person.toJson()).toList());
