This pure Dart and and dependency-free package provides functionality for working with HTTP status codes in a functional programming style.

Features

• Extends num types with helper functional methods (when, map, maybeWhen, etc.) for handling HTTP status codes.
• Provides StatusCode enum for easy handling of all IANA registered HTTP status codes (also in functional style).
• Provides methods for parsing HTTP status codes from String and num types, and much more.

Use your favorite HTTP client libraries such as http or dio and take advantage of this package's functional API to easily handle HTTP status codes in your Dart project.

final statusCode = response.statusCode; // int status code of response.
if (!response.statusCode.isStatusCode) return null; // Checks if statusCode >=100 & <600.
  final registeredCode = response.statusCode.toRegisteredStatusCode();
  // Handle any type of registered status codes via functional `whenOrNull` method:
  return registeredCode?.whenOrNull(
    okHttp200: () => _parseResponse(response.body),
    badRequestHttp400: () => _showError(),
    orElse: () => _handleUnknownResponse(response),
  );
