GrowingBarWaveIndicator class

An animated loading indicator with three vertical bars that grow and shrink in a wave pattern.

Bars expand and contract through keyframe animation, creating a wave effect that travels from left to right. Each bar is vertically centered and grows symmetrically from its center point.

Example:

GrowingBarWaveIndicator(
  size: 80,
  color: Colors.teal,
  duration: Duration(milliseconds: 1400),
  borderRadius: 5,
)
