innerArcEnd property
Offset
innerArcEnd
when drawing a donut in one stroke, starting from the outer perimeter, this is the third point, it lies on the inner perimeter of the donut
Implementation
Offset get innerArcEnd {
double x3 = radiusStart * cos(angleStart + swipe) + center.dx;
double y3 = radiusStart * sin(angleStart + swipe) + center.dy;
return Offset(x3,y3);
}
