toString method

@override String toString([ void _ ])

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([void _]) {
  var txt = text;
  if (txt != null) {
    txt = txt
        .replaceAll('\n', r'\n')
        .replaceAll('\r', r'\r')
        .replaceAll('\t', r'\t');
  } else {
    txt = '<no text>';
  }
  return "[@$tokenIndex,$startIndex:$stopIndex='$txt',<$type>" +
      (channel > 0 ? ',channel=$channel' : '') +
      ',$line:$charPositionInLine]';
}
