OvalBorder class
A border that fits an elliptical shape.
Typically used with ShapeDecoration to draw an oval. Instead of centering
the Border to a square, like CircleBorder, it fills the available space,
such that it touches the edges of the box. There is no difference between
CircleBorder(eccentricity = 1.0) and OvalBorder(). OvalBorder works as
an alias for users to discover this feature.
See also:
- CircleBorder, which draws a circle, centering when the box is rectangular.
- Border, which, when used with BoxDecoration, can also describe an oval.

Properties
- dimensions → EdgeInsetsGeometry
-
The widths of the sides of this border represented as an EdgeInsets.
no setterinherited
- eccentricity → double
-
Defines the ratio (0.0-1.0) from which the border will deform
to fit a rectangle.
When 0.0, it draws a circle touching at least two sides of the rectangle.
When 1.0, it draws an oval touching all sides of the rectangle.
