toString method

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

String toString() {
  double angle = math.atan2(dy, dx);
  String className = runtimeType.toString();
  int lastDotPos = className.lastIndexOf('.');
  String name = className.substring(lastDotPos + 1);
  return "  $name: $p0  - $p1 $quadrant: $angle    $label";
}
