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() {
  if (label.isNotEmpty) {
    return label;
  }

  var name = '$runtimeType';
  final index = name.indexOf('<');
  if (index != -1) {
    name = name.substring(0, index);
  }

  if (name.endsWith('Parser')) {
    name = name.substring(0, name.length - 6);
  }

  name = name[0].toLowerCase() + name.substring(1);
  return name;
}
