An animated loading indicator with two rows of three bars that grow and shrink in sequence.

The top row bars grow upward while the bottom row bars grow downward, with one column animating at a time in a sequential pattern from left to right.

Example:

DoubleRowBarsIndicator(
  size: 80,
  color: Colors.green,
  duration: Duration(milliseconds: 1500),
  borderRadius: 3,
)
