What happened?

This is the same thing originally posted in #1887 which was closed.

Expected
As a user, when I dismiss a keyboard, the bottom sheet modal should go back to its original position

Actual
on iOS the bottom sheet does not go back to default/previous position.

Similar thing is happening for me. I have keyboardBehavior="interactive" when I open the keyboard the sheet moves up and when I dismiss the keyboard sheet remains at the top. This part of the code is not returning the correct index. I have managed to put a fix in my locally installed package code. Basically the currentIndex in this code is incorrect when keyboard closes:

I fixed it locally by going into the node_modules and gorhom folder, finding this section in BottomSheet component and adding this in the if statement:

if (
source === ANIMATION_SOURCE.KEYBOARD &&
keyboardBlurBehavior === KEYBOARD_BLUR_BEHAVIOR.restore &&
keyboardStatus === KEYBOARD_STATUS.HIDDEN &&
animatedContentGestureState.value !== State.ACTIVE &&
animatedHandleGestureState.value !== State.ACTIVE
) {
isInTemporaryPosition.value = false;
// return the previously active detent position when available,
// otherwise fall back to the first detent
const nextPosition =
currentIndex >= 0 && detents && currentIndex < detents.length
? detents[currentIndex]
: detents[0];
return nextPosition;
}

@HassanKhan96 it doesn't work in my case.
