PolygonBorder class

A border that fits a polygon-shaped border with its number of sides equal to sides, rotated by rotate degrees within the rectangle of the widget it is applied to.

To round the edges of the polygon, pass the desired angle to borderRadius. There is a known issue where adding a borderRadius will reduce the size of the polygon.

See also:

• BorderSide, which is used to describe the border of the polygon.

override

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}) → 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

A string representation of this object.
