Scroll handle is not positionned properly when scrolling the recycling view

Hello and thank you for this project.

I have noticed an issue when the list contains a small number of elements. It can be reproduced by only keeping the first 20 or so items in the countries.json file of the sample app.

When scrolling using the scroll handle everything is going fine :

but when dragging down the list itself to the end, the scroll handle doesn’t go until the bottom, even though I have reached the last element in the list :

Is it related to the TODO item mentioned in the README ( Make handle size flexible to item count in adapter) or is it a bug?

Since this project hasn’t been updated in a year and I haven’t extensively tested this solution, I’m leaving this here as a comment instead of submitting a PR in case anyone else has come across this issue.

There seems to be an issue with the math onScrolled

Ended up replacing https://github.com/quiph/RecyclerView-FastScroller/blob/v1.0.0/recyclerviewfastscroller/src/main/java/com/qtalk/recyclerviewfastscroller/RecyclerViewFastScroller.kt#L906-L909 with

val availableTrackLength = extent.toFloat() - handleLength
val scrollPositionPercent = (offset.toFloat() / (range - extent))
val finalOffset = availableTrackLength * scrollPositionPercent

moveHandle(finalOffset)
