positioned method
Positions this widget relative to a Stack's edges.
Specify at most two of left, right, and width, and at most two of
top, bottom, and height. Opposing edges determine the child's size.
Positioned children do not determine the stack's size.
Keep this wrapper outside render-object wrappers:
child.padding(insets).positioned(bottom: 0) belongs in stack children.
