ShimmeringSquareGridIndicator class

An animated loading indicator with a 3x3 grid of squares that shimmer diagonally.

Nine squares arranged in a grid display a shimmer effect that travels diagonally from top-left to bottom-right. Squares brighten and fade based on their distance from the shimmer wave using a gaussian-like intensity curve.

Example:

ShimmeringSquareGridIndicator(
  size: 80,
  color: Colors.indigo,
  duration: Duration(milliseconds: 1500),
)
