SquareWaveGridIndicator class

An animated loading indicator with a 3x3 grid of squares that scale in a wave pattern.

Nine squares arranged in a grid animate independently with staggered timing. Each square scales down and back up in a smooth wave motion, with delays creating a diagonal wave pattern from bottom-left to top-right across the grid.

Example:

SquareWaveGridIndicator(
  size: 50.0,
  color: Colors.blue,
  duration: Duration(milliseconds: 1500),
)
