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() {
  final location = StringBuffer(path);
  if (line != null) {
    location.write(':$line');
    if (column != null) {
      location.write(':$column');
    }
  }
  return '$location: $code: $message';
}
