在flutter中解析JSON数组

import 'dart:convert';

void main() {
  String jsonStr = '[{"name":"Alice","age":25},{"name":"Bob","age":30}]';
  List<dynamic> jsonData = jsonDecode(jsonStr);

  List<Person> persons = [];
  for (var data in jsonData) {
    persons.add(Person.fromJson(data));
  }

  print(persons);
}

class Person {
  final String name;
  final int age;

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

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

  @override
  String toString() {
    return 'Name: $name, Age: $age';
  }
}

[Name: Alice, Age: 25, Name: Bob, Age: 30]
