Methods

add(ShapeBorder other, {bool reversed = false}) ShapeBorder?
Attempts to create a new object that represents the amalgamation of this border and the other border.
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 this to another ShapeBorder (possibly of another class).
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
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.
