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() {
  var s = StringBuffer();
  s.write('{');

  if (positionalParameters != null) {
    s.write('positionalParameters: ');
    s.write(positionalParameters);
  }

  if (optionalParameters != null) {
    if (s.length > 1) s.write(', ');
    s.write('optionalParameters: ');
    s.write(optionalParameters);
  }

  if (namedParameters != null) {
    if (s.length > 1) s.write(', ');
    s.write('namedParameters: ');
    s.write(namedParameters);
  }

  s.write('}');

  return s.toString();
}
