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(),
