        children: [
          ArcAnimator(
            curve: Curves.easeInOutSine,
            begin: Offset(60, 60),
            end: Offset(size.width - 60, size.height - 60),
            controller: controller,
            statusListener: (status) => print(status),
            offsetChanging: (offset) => print(offset),
            child: FloatingActionButton(
              onPressed: () => controller.forward(), // You don't need controller.reverse()
            ),
