CircleBorder class
A border that fits a circle within the available space.
Typically used with ShapeDecoration to draw a circle.
The dimensions assume that the border is being used in a square space. When applied to a rectangular space, the border paints in the center of the rectangle.
See also:
- BorderSide, which is used to describe each side of the box.
- Border, which, when used with BoxDecoration, can also describe a circle.
