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.

inherited

copyWith({BubbleDirection? direction, double? arrowHeight, double? arrowAngle, double? arrowQuadraticBezierLength, BubblePosition? position, BubbleBoxBorder? border, BorderRadius? radius, double? smooth, double? dashedWidth, double? dashedGap, Gradient? gradient}) → BubbleShapeBorder

copyWith the border

getInnerPath(Rect rect, {TextDirection? textDirection}) → Path

Create a Path that describes the inner edge of the border.

override

getOuterPath(Rect rect, {TextDirection? textDirection}) → Path

Create a Path that describes the outer edge of the border.

override

lerpFrom(ShapeBorder? a, double t) → ShapeBorder?

Linearly interpolates from another ShapeBorder (possibly of another class) to this.

inherited

lerpTo(ShapeBorder? b, double t) → ShapeBorder?

Linearly interpolates from this to another ShapeBorder (possibly of another class).

inherited

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.

override

paintInterior(Canvas canvas, Rect rect, Paint paint, {TextDirection? textDirection}) → void

Paint a canvas with the appropriate shape.

inherited

scale(double t) → ShapeBorder

Creates a copy of this border, scaled by the factor t.

override

toString() → String
