An Offset that represents the absolute distance from the origin, or 0, of the ScrollPosition expressed in the associated Axis.
Used by EdgeDraggingAutoScroller to progress the position forward when a drag gesture reaches the edge of the Viewport.
Implementation
Offset get deltaToScrollOrigin {
return switch (axisDirection) {
AxisDirection.up => Offset(0, -position.pixels),
AxisDirection.down => Offset(0, position.pixels),
AxisDirection.left => Offset(-position.pixels, 0),
AxisDirection.right => Offset(position.pixels, 0),
};
