toString method Null safety

  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() {
  var constructor = using;
  switch (using) {
    case 'link text':
      constructor = 'linkText';
      break;
    case 'partial link text':
      constructor = 'partialLinkText';
      break;
    case 'tag name':
      constructor = 'tagName';
      break;
    case 'class name':
      constructor = 'className';
      break;
    case 'css selector':
      constructor = 'cssSelector';
      break;
  }
  return 'By.$constructor($value)';
}
