The last value the measure function associated with this node Component returned for the height. This is used together with lastHeightSpec to implement measure caching. Also sets the last value the measure function associated with this node Component returned for the height.
The last value the measure function associated with this node Component returned for the width. This is used together with lastWidthSpec to implement measure caching. Also sets the last value the measure function associated with this node Component returned for the width.
The direction this node was last laid out in. A layout can depend on it, so its last measurement is only reused in the same direction.
