ShapeBorder class
Base class for shape outlines.
This class handles how to add multiple borders together. Subclasses define various shapes, like circles (CircleBorder), rounded rectangles (RoundedRectangleBorder), continuous rectangles (ContinuousRectangleBorder), or beveled rectangles (BeveledRectangleBorder).
See also:
- ShapeDecoration, which can be used with DecoratedBox to show a shape.
- Material (and many other widgets in the Material library), which takes a ShapeBorder to define its shape.
- NotchedShape, which describes a shape with a hole in it.

Abstract const constructor. This constructor enables subclasses to provide
const constructors so that they can be used in const expressions.

this
border and theother
border. [...]@protected -

lerpFrom(
ShapeBorder a, double t) → ShapeBorder -
Linearly interpolates from another ShapeBorder (possibly of another
class) to
this
. [...]@protected -
lerpTo(
ShapeBorder b, double t) → ShapeBorder -
Linearly interpolates from
this
to another ShapeBorder (possibly of another class). [...]@protected -

scale(
double t) → ShapeBorder -
Creates a copy of this border, scaled by the factor

) → String -
Returns a string representation of this object.
