toString method

@override String toString()

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 parts = <String>[];
  if (source != null) parts.add('source=$source');
  if (medium != null) parts.add('medium=$medium');
  if (campaign != null) parts.add('campaign=$campaign');
  if (term != null) parts.add('term=$term');
  if (content != null) parts.add('content=$content');
  return 'UTMParameters(${parts.join(', ')})';
}
