ServerException class

Exception for HTTP 5xx server errors.

Thrown when the My Fuel Orders backend encounters an internal server error, database failure, or other server-side issue. Typically maps to HTTP status codes 500-599.

The default message is user-friendly and suggests the issue is temporary.

Example:

if (response.statusCode >= 500) {
  throw ServerException(
    message: 'Order service temporarily unavailable',
    originalException: dioError,
  );
}
