这样做：

private var _binding: View? = null
  /*
   *Transform to immutable - use this for updating binding
   *properties like in data binding
   */
   private val binding: View get() = _binding!!

  override fun onCreateView(
        inflater: LayoutInflater,
        container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View {       
        _binding = FragmentPhotoDetailBinding.inflate(inflater, container, false)
        binding.apply {
                lifecycleOwner = viewLifecycleOwner
                viewBinding = this
                vm = viewModel
            }
        }
        return binding.root!!
    }

  override fun onDestroy(){
     super.onDestroy()
    //Nullify since it is not automatically garbage collected
     _binding = null
}

如果您希望重用先前已膨胀，则可以在onCreateView中对_binding添加空检查，并删除onDestroy中_binding的无效

if (_binding == null) { 
   _binding = FragmentPhotoDetailBinding.inflate(inflater, container, false)
}
