PaletteBorderController class

Controller for imperatively controlling a PaletteBorder.

Use this when you need to trigger border effects without rebuilding the widget tree (e.g., from a service or callback).

final controller = PaletteBorderController();

// Later:
controller.flash(Colors.red);
controller.pulse(Colors.orange, count: 2);
controller.set(Colors.blue);
controller.clear();
