Custom carousel indicator points

# introduce


In order to avoid wrong use and bring you a bad development experience, please read the following precautions carefully before using the component, which can help you avoid some mistakes.

  • This component depends on the swiper component, please use it with the swiper component
  • width and height should not be set too large or too small unless necessary
  • swiper-item should be kept within a certain amount as much as possible, otherwise the indicator point may exceed the screen
  • Do not support vertical pointers
