HttpStatusCode

The HttpStatusCode class provides a centralized collection of commonly used HTTP status codes, grouped by their respective categories: success, redirection, client error, and server error.

This makes it easier to avoid magic numbers, improve code readability, and reduce typos when working with HTTP responses.

✅ Usage Example

if (response.statusCode == HttpStatusCode.ok) {
  print('Request succeeded!');
} else if (response.statusCode == HttpStatusCode.notFound) {
  print('Resource not found.');
}
