Arc class

An arc defined by a center, radius, start angle, and end angle.

Angles are in radians. The arc sweeps counter-clockwise from startAngle to endAngle.

Constructors

Arc({required Point center, required double radius, required Rad startAngle, required Rad endAngle})
const
Arc.fromDegrees({required Point center, required double radius, required double startDeg, required double endDeg})
Create an arc from degrees instead of radians
factory
