fragment中销毁binding时机

不建议这么使用
           thisRef.viewLifecycleOwner.lifecycle.addObserver(object : LifecycleObserver {
                @OnLifecycleEvent(Lifecycle.Event.ON_DESTROY)
                fun onDestroyView() {
                    Log.e("taggg", "onDestroyView viewLifecycleOwner$this")
                    _binding = null
                }
            })
因为这会导致比fragment更快的执行onDestroyView方法
