toString method

  1. @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 represetion.

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.


String toString() {
  switch (this) {
    case array:
      return 'array';
    case boolean:
      return 'boolean';
    case integer:
      return 'integer';
    case number:
      return 'number';
    case nullValue:
      return 'null';
    case object:
      return 'object';
    case string:
      return 'string';
  return null;
