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.

class) to
this. [...]@protected -

ShapeBorder b, double t) → ShapeBorder -
Linearly interpolates from
thisto another ShapeBorder (possibly of another class). [...]@protected -
paint(
Canvas canvas, Rect rect, { TextDirection textDirection }) → void - Paints the border within the given Rect on the given Canvas. [...]
-
scale(
double t) → ShapeBorder -

t. [...] -
toString(
) → String -
Returns a string representation of this object.
