CircularProgressIndicator does not disposed when used in the CaouselSlider
When i use CircularProgressIndicator in the CarouselSlider, a new instance created in each loop. I tried with different carousel widgets. But same issue occurred.
To reproduce issue, just create a new project, add CarouselSlider and CircularProgressIndicator, explore widget tree.
