كيف تتعامل مع الشبكات والواجهات البرمجية في Flutter؟

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

// GET request
Future<List<User>> fetchUsers() async {
  final response = await http.get(Uri.parse('https://api.example.com/users'));
  if (response.statusCode == 200) {
    final List data = jsonDecode(response.body);    // parse JSON
    return data.map((json) => User.fromJson(json)).toList();
  } else {
    throw Exception('Failed to load users');         // handle errors
  }
}

// POST request
await http.post(
  Uri.parse('https://api.example.com/users'),
  headers: {'Content-Type': 'application/json'},
  body: jsonEncode({'name': 'Ann'}),
);
