toString method

  1. @override
String toString()
override

A string representation of this object.

Some classes have a default textual representation, often paired with a static parse function (like int.parse). These classes will provide the textual representation as their string representation.

Other classes have no meaningful textual representation that a program will care about. Such classes will typically override toString to provide useful information when inspecting the object, mainly for debugging or logging.

Implementation

@override
String toString() {
  final buffer = StringBuffer('ScrapingException: $message');

  if (url != null) {
    buffer.write(' (URL: $url)');
  }

  if (statusCode != null) {
    buffer.write(' (Status: $statusCode)');
  }

  if (originalException != null) {
    buffer.write(' (Cause: $originalException)');
  }

  return buffer.toString();
}
