ShadowDotsIndicator class
An animated loading indicator with three dots that fade in and out sequentially.
Three horizontally aligned dots display a traveling highlight effect by modulating their opacity. The highlight moves from left to right continuously, with dots at different distances from the highlight showing different opacity levels (full, medium, low).
Example:
ShadowDotsIndicator(
size: 80,
color: Colors.blue,
duration: Duration(milliseconds: 1200),
