operator - method

@override Size operator -(Point<num> other)

Subtract other from this, as if both points were vectors.

Returns the resulting "vector" as a Point.

Example:

var point = const Point(10, 100) - const Point(10, 10); // Point(0, 90)
point = const Point(-10, -20) - const Point(100, 100); // Point(-110, -120)

Implementation

@override
Size operator -(Point other) {
  return Size(x - other.x, y - other.y);
}
