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 buffer = StringBuffer('POLYGON ');
  if (hasZ) {
    buffer.write('Z');
  }
  if (hasM) {
    buffer.write('M');
  }

  if (hasZ || hasM) {
    buffer.write(' ');
  }

  buffer.write(toText());
  return buffer.toString();
}
