REST API Integration in Flutter

Almost every modern app communicates with a backend. Clean API integration keeps your code maintainable.

Use a Service Layer

Avoid calling HTTP directly from UI. Instead create a dedicated service class.

class ApiService {
  final Dio _dio = Dio();

  Future<Response> getUsers() async {
    return _dio.get('/users');
  }
}

Error Handling

Always handle network failures:

try {
  final res = await api.getUsers();
} catch (e) {
  print('Network error');
}

Best Practices

• Use interceptors
• Separate models
• Handle timeouts
• Cache when possible

Conclusion

A well-structured API layer makes your Flutter app production-ready and easier to maintain.
