Unable to scroll a page smoothly while using drag() method. Is there any scroller method to scroll a page?

I am using `drag()` method for scrolling a list of items, and then using `click_on()` to click on an specific item but the `drag()` method scrolls the list upto last down so the `click_on()` method is getting fail to click and raising error.

Start by reproducing the reported behavior in the telenium automation for a Kivy list: use drag() to scroll and click_on() to select an item. Read the implementation and available tests for these methods, then verify whether scrolling can stop at a predictable position so the requested item remains clickable.
