Point.vector(Vector v)

Factory constructor which reads x-y-z-values from a vector

Implementation

factory Point.vector(Vector v) {
  int length = v.length;
  assert(length == 2 || length == 3, 'Point must have 2 or 3 dimensions');

  if (length == 2) {
    return Point._(v[0], v[1], 0);
  }

  return Point._(v[0], v[1], v[2]);
}
