AnimatedSelectionAreaPaint class

A selection highlight widget that paints rectangles with an animated gradient. The gradient rotates continuously when withAnimation is true.

All animation parameters are customizable:

  • colors: the gradient colors (defaults to a purple→pink→gold rainbow)
  • duration: one full rotation cycle (default 4 seconds)
  • curve: easing curve for the rotation (default bounceInOut)
