For the nav pane issues, maybe we can also upstream some of this work into react-navigation drawer?

@AgneLukoseviciute yeah that's a good idea! Which issue were you looking at specifically? Most of these were resolved with just adding an accesssibilityLabel so not sure the expected output when using react-navigation drawer

I think we should be able to add the accessibilityState expanded prop (which fixed #227) to their DrawerToggleButton so the added accessibility is provided for "free" and apps don't have to do extra work.

And then for the one where you added accessibilityLabels (#226), ideally react-navigation would just use the text of the button as the default accessibilityLabel so we don't need to set it explicitly.
