ShapeBorder class abstract
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.

Methods
-
add(
ShapeBorder other, {bool reversed = false}) → ShapeBorder? -
Attempts to create a new object that represents the amalgamation of
thisborder and theotherborder. -
getInnerPath(
Rect rect, {TextDirection? textDirection}) → Path - Create a Path that describes the inner edge of the border.
-
getOuterPath(
Rect rect, {TextDirection? textDirection}) → Path - Create a Path that describes the outer edge of the border.
-
lerpFrom(
ShapeBorder? a, double t) → ShapeBorder? -
Linearly interpolates from another ShapeBorder (possibly of another
class) to
this. -
lerpTo(
ShapeBorder? b, double t) → ShapeBorder? -
Linearly interpolates from
thisto another ShapeBorder (possibly of another class). -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.

-
paint(
Canvas canvas, Rect rect, {TextDirection? textDirection}) → void - Paints the border within the given Rect on the given Canvas.
-
paintInterior(
Canvas canvas, Rect rect, Paint paint, {TextDirection? textDirection}) → void - Paint a canvas with the appropriate shape.
-
scale(
double t) → ShapeBorder -
Creates a copy of this border, scaled by the factor
t. -
toString(
) → String -
A string representation of this object.
