如何在flutter中解析JSON文件

dependencies:
  http: ^0.13.0

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

Future<void> fetchAndParseJson() async {
  final response = await http.get(Uri.parse('https://example.com/api/data.json'));
  if (response.statusCode == 200) {
    final jsonData = jsonDecode(response.body);
    // 在这里对jsonData进行处理
  } else {
    throw Exception('Failed to fetch JSON data');
  }
}

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

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

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

final jsonData = jsonDecode(response.body);
final userList = (jsonData as List<dynamic>).map((json) => User.fromJson(json)).toList();
