Thanks for your answer.
Actually, could you tell me if the "predicted" item height calculation is important or maybe we could get rid of it in a rather simple situation ? I will experiment some variations on my actual project anyway.

Unfortunately, I cannot give you a clear-cut "yes" or "no". It really depends on your use case. At the very least, you will need to provide a ballpark figure that represents the average size of your list item so that the total scroll area can be calculated. This, however, might be problematic, if your items have the potential to vary greatly in size and these size differences are not evenly distributed across the list (averaging will be harder). But, by all means, you can experiment and fine tune/simplify the whole prediction part based on your needs. I've used a more general approach in the article.

I see, thanks a lot for taking your time on this.
My goal is to catch what is still quite "automagic" in the implementation.
I think that the official documentation is not enough to say the least.
