@ferrannp could you please test this pr :)

Hey @gorhom, mmm it seems that it is still happening. In the code I cannot share happens all the time. In the playground https://github.com/ferrannp/bottom-sheet-playground happens less but if you keep reloading JS, you can see it still happens. See:

In this gif, the first reload is ok, the second one has the flash. It is a bit random, sometimes flashes on mount, sometimes not, etc.

FYI @gorhom this still happens even with the #246 fix.

[gorhom]

[ferrannp]

@ferrannp hmm i can't reproduce it 😩 , i would suggest to merge this pr since it provide more a stable animatedIndex ?

[ferrannp]

Yeah let's try and release @gorhom. Then I will try again with real version and try to reproduce it again.
