   好像不支持，自己做个简单的移植就可以了

   import androidx.viewpager2.widget.ViewPager2
   import net.lucode.hackware.magicindicator.MagicIndicator
   
   /**
    * 新版页卡的绑定辅助工具，移植自 [net.lucode.hackware.magicindicator.ViewPagerHelper]。

   class ViewPager2Helper {
       companion object {
           fun bind(magicIndicator: MagicIndicator, viewPager: ViewPager2) {
               viewPager.registerOnPageChangeCallback(object : ViewPager2.OnPageChangeCallback() {
                   override fun onPageScrolled(
                       position: Int,
                       positionOffset: Float,
                       positionOffsetPixels: Int
                   ) {
                       magicIndicator.onPageScrolled(position, positionOffset, positionOffsetPixels)
                   }
   
                   override fun onPageSelected(position: Int) {
                       magicIndicator.onPageSelected(position)
                   }
   
                   override fun onPageScrollStateChanged(state: Int) {
                       magicIndicator.onPageScrollStateChanged(state)
                   }
               })
           }
       }
   }
