StacOffset class

A Stac representation of a 2D offset (displacement).

This class represents a displacement in 2D space with horizontal (dx) and vertical (dy) components. It's commonly used for positioning elements, defining shadow offsets, or specifying translation transformations.

{@tool snippet} Dart Example:

const StacOffset(dx: 10.0, dy: 20.0)

{@end-tool}

{@tool snippet} JSON Example:

{
  "dx": 10.0,
  "dy": 20.0
}

{@end-tool}
