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 buf = StringBuffer()
    ..write(x)
    ..write(',')
    ..write(y);
  if (is3D) {
    buf
      ..write(',')
      ..write(z);
  }
  if (isMeasured) {
    buf
      ..write(',')
      ..write(m);
  }
  return buf.toString();
}
