GridPaper class Null safety

A widget that draws a rectilinear grid of lines one pixel wide.

Useful with a Stack for visualizing your layout along a grid.

The grid's origin (where the first primary horizontal line and the first primary vertical line intersect) is at the top left of the widget.

The grid is drawn over the child widget.
