如何使用flutter解析此api json？

dependencies:
  http: ^0.13.3

import 'package:http/http.dart' as http;

Future<void> fetchData() async {
  final response = await http.get(Uri.parse('https://api.example.com/data'));
  if (response.statusCode == 200) {
    // 解析JSON数据
    final jsonData = json.decode(response.body);
    // 处理数据
    // ...
  } else {
    // 处理错误
    // ...
  }
}

import 'dart:convert';

{
  "name": "John",
  "age": 25,
  "email": "john@example.com"
}

class User {
  final String name;
  final int age;
  final String email;

  User({required this.name, required this.age, required this.email});

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

final jsonData = json.decode(response.body);
final user = User.fromJson(jsonData);
print(user.name); // 输出：John
