Im not able to reproduce it on the examples but happens on a fresh react native init project Flicker and modal gets pushed up slightly when pressing on a TextInput. Happens with normal BottomSheet aswell but no flicker, just the sheet getting pushed up slightly. seems to happen only on android

@gorhom I believe latest update resolves this issue. I have added keyboardBehavior as none i.e. I don’t want anything to happen if keyboard is opened or closed. I upgraded to latest version 3.6.2 but somehow flicker is still there in the component when we focus on the text input. Not able to figure out what I missed here. Can you please enlighten me ?
