Methods

add(ShapeBorder other, {bool reversed = false}) → TxBorder?

Attempts to create a new object that represents the amalgamation of this border and the other border.

override

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

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

inherited

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

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

inherited

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

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

override

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

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

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

paint(Canvas canvas, Rect rect, {TextDirection? textDirection, BoxShape shape = BoxShape.rectangle, BorderRadius? borderRadius}) → 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) → TxBorder

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

override

toString() → String
