SwappingDotsIndicator class

An animated loading indicator with three dots that rotate positions with an arc motion.

Three horizontally aligned dots continuously rotate positions. The rightmost dot jumps to the leftmost position by traveling in an upward arc, while the other two dots slide linearly to the right. This creates a smooth cycling effect.

Example:

SwappingDotsIndicator(
  size: 80,
  color: Colors.deepOrange,
  duration: Duration(milliseconds: 1200),
)
