hitTestInput method Null safety

  1. @override
DisplayObject? hitTestInput(
  1. num localX,
  2. num localY
)
override

Evaluates this display object to see if the coordinates localX and localY are inside this display object.

If the coordinates are inside, this display object is returned; null otherwise.

localX and localY are relative to to the origin (0,0) of this display object (local coordinates).

Implementation

@override
DisplayObject? hitTestInput(num localX, num localY) {
  if (localX < 0.0 || localX >= bitmapData.width) return null;
  if (localY < 0.0 || localY >= bitmapData.height) return null;
  return this;
