Infinite list?

[wtlgo]

The description of the library says that it supports an "Infinite list", but I can't figure out how to achieve that.
May someone explain, please?

@wtlgo It means that when you have e.g 5 items, and you're on item-4 (the last one), you will see item-0 on the right side, so you can infinitely scroll with a loop

Oh, wouldn't that be called a "looped" gallery then? Well, anyway.
If so, is there any way to feed ~300k items into the gallery without exploding? The performance monitor shows that it tries to render all 300k views at once, and it is a very computationally intensive task.
I came up with an idea to split it into batches of 10 and then feed only 3 batches at once. And whenever the index goes out of the range [10, 20) I switch to another 3 batches and replace the index with 10 or 20 respectfully via ref.current.setIndex(idx). It works, but whenever it switches between batches I get an ugly "blink" because the data and the index are updated at the same time. So, maybe there's a better way?
