Clean up any references to the binding class instance in the fragment's onDestroyView()

[AlexTrotsenko]

In Readme it's written, that

DataBinding-ktx is saving memory because of cleaning up the binding variable having the view tree after onDestroyView.

I see it's well aligned with note in official documentation:

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

But briefly looking though the code I was not able to find clean-up of the binding.

Could you please advice how clean-up is achieved? I am a bit anxious about keeping additional memory unintentionally.

Thank you for asking your question.

The binding is stored by View's tag. The view is released after onDestroyView. And the view's tag is also released. Therefore, the binding is clean-up.
