BoxShadow class
A shadow cast by a box.
BoxShadow can cast non-rectangular shadows if the box is non-rectangular (e.g., has a border radius or a circular shape).
This class is similar to CSS box-shadow.

- Canvas.drawShadow, which is a more efficient way to draw shadows.
- PhysicalModel, a widget for showing shadows.
- kElevationToShadow, for some predefined shadows used in Material Design.
- Shadow, which is the parent class that lacks spreadRadius.
