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() {
  return '''
  {
    ${title != null ? 'title: ${title!.toString()},' : ''}
    ${labels != null ? 'labels: ${labels!.toString()},' : ''}
    ${min != null ? 'min: $min,' : ''}
    ${max != null ? 'max: $max,' : ''}
    ${gridLineWidth != null ? 'gridLineWidth: $gridLineWidth' : ''}
  }
  ''';
}
