Below code snippet helped me solve this issue where i am toggling between visibility of different views in layout and height is automatically changing for my bottom sheet.

override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
    return inflater.inflate(R.layout.your_bottom_sheet_layout, container, false)
}

override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
    val dialog = super.onCreateDialog(savedInstanceState) as BottomSheetDialog
    dialog.setContentView(R.layout.your_bottom_sheet_layout)

    dialog.setOnShowListener {
        val castDialog = it as BottomSheetDialog
        val bottomSheet = castDialog.findViewById(R.id.design_bottom_sheet)
        val behavior = BottomSheetBehavior.from(bottomSheet)
        behavior.state = BottomSheetBehavior.STATE_EXPANDED
        behavior.setBottomSheetCallback(object : BottomSheetBehavior.BottomSheetCallback() {
            override fun onStateChanged(bottomSheet: View, newState: Int) {
                if (newState == BottomSheetBehavior.STATE_DRAGGING) {
                    behavior.state = BottomSheetBehavior.STATE_EXPANDED
                }
            }

            override fun onSlide(bottomSheet: View, slideOffset: Float) {}
        })
    }

    return dialog
}
