toString method

  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() {
  final location = [
    if (file != null) file,
    if (span != null) ...['${span!.line + 1}', '${span!.column + 1}'],
  ].join(':');
  return location.isEmpty ? message : '$location: $message';
}
