Animate bottom sheet when unmounts

[andrecrimb]

Feature Request

Why it is needed

Bottom sheet has currently available the animateOnMount prop which:

... initially mount the sheet closed and when it is mounted and calculated the layout, it will snap to initial snap point index.

Our team came across a use case, where we need to have the same animation but when the BS unmounts (some sort of exiting animation).
I believe this feature is quite beneficial for those who need to handle several bottom sheets and seek some sort of a continuation flow. (eg. one BS slides down and another one slides up)

Possible implementation

Reanimated 2 allows animated views to have exiting animations.

Code sample

I imagine the use of animatedOnUnmount (or animateOnExiting) something like:

 return (
   <BottomSheet
      animateOnExiting={true}
      {...otherProps}
    />
)
