MaterialPointArcTween constructor

MaterialPointArcTween({Offset begin, Offset end })

Creates a Tween for animating Offsets along a circular arc.

The begin and end properties must be non-null before the tween is first used, but the arguments can be null if the values are going to be filled in later.

MaterialPointArcTween({
  Offset begin,
  Offset end,
}) : super(begin: begin, end: end);
