Hi guy, I would life to ask about Android's ViewBinding .

In the documentation here, it suggest to clear the binding reference, in on onDestroyView() :

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

because:

"Note: Fragments outlive their views. Make sure you clean up any references to the binding class instance in the fragment's onDestroyView() method."

My questions are:

1. When exactly would the fragment outlive the views? Is it when the fragment is added to the backstack?
2. Does avoiding a global reference to the _binding and simply referencing it locally in onViewCreated() ensures that I wont leak the viewBinding? ex.

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    super.onViewCreated(view, savedInstanceState)
    val binding = SomeViewBinding.inflate(view)
}
