Is it mandatory to set databinding obejct to null inside onDestroyView()?

Issue

I read some articles where it is said that the best practice is to set databinding obejct to null inside onDestroyView() in a fragment:

override fun onDestroyView() {
    super.onDestroyView()
    dataBinding = null
}

I've also seen this video where this practice is not even mentioned. I personally don't understand if this practice makes sense or not. Please provide some info about this issue because I really don't know how to go further. Thanks

Solution

This is not necessary. databinding is just auto generated by compile system. You can go to see the generated source code. Just use databinding object as same as common propertys.
