先使用popBackStack弹出fragmentB,C 页面跳转到A 然后在使用clearBackStack(fragmentC),然后setRestoreState到B，还会有fragmentC的onCreate，当前栈顶为C，显示为C，c不应该被clearBackStack了吗？

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
        tagsPageBinding.toUserFragment.setOnClickListener {
            findNavController().popBackStack(R.id.home_fragment,inclusive = false,saveState = true)
        }
    }

 override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
        homePageBinding.homeButton.setOnClickListener {
            if(flag){
                findNavController().navigate(R.id.category_fragment)
            }else{
                findNavController().navigate(R.id.category_fragment,null,NavOptions.Builder().setRestoreState(true).build())
            }

        }
        homePageBinding.clearButton.setOnClickListener {
            val navController : NavController =  findNavController()
            navController.clearBackStack(R.id.tags_fragment)
            flag = false
        }
    }
