VerticalAffinity class

Represents a widget that allows to place a widget above and below the child widget in horizontal direction which is controlled by affinity.

If affinity is set to Affinity.start, the leading widget will be placed above the child widget and the trailing widget will be placed below the child widget.

If affinity is set to Affinity.end, the leading widget will be placed below the child widget and the trailing widget will be placed above the child widget.
