Navigator.ScrollView not yet there?

In React.Native it seems to be quite challenging to have this collapsible toolbar and toolbar animations implemented. In my app I need the behavior similar to what you have in AirBnb app at the top – a form with fields that animates to toolbar and toolbar itself hides when user scrolls.

Leland have mentioned in his talk this Navigator.ScrollView component that, supposedly, can help achieve such behavior via native-navigation library. But, I didn't find it in the docs.

How long can it take to have in the library?
Does it make sense for me to wait or rather invest into other possible solutions?

Start by checking the native-navigation documentation and the referenced Navigator.ScrollView component. Determine whether it exists, is planned, or is outside the library's scope for collapsible and hiding toolbars; document the status and any supported alternative in the issue or project documentation.
