getViewLifecycleOwnerLiveData
Retrieve a LiveData which allows you to observe the lifecycle of the Fragment's View.
This will be set to the new LifecycleOwner after onCreateView returns a non-null View and will set to null after onDestroyView.
Overriding this method is no longer supported and this method will be made final
in a future version of Fragment.
Return
A LiveData that changes in sync with getViewLifecycleOwner.
