Question: What does pageKey exactly do?

[Shawn-sudo]

Hi, I'm just wondering what pageKey exactly do in .addPageRequestListener((pageKey) {}) and .appendPage([items_here], nextPageKey).

README only shows how to use it (like when appending a page, nextPageKey = pageKey + newItems.length), and everything seems to work fine even when I just put any random number for pageKey and nextPageKey, so what do they do?

pageKey tells you which page you are on. this can be anything from a number going up to a string that tells the database cursor where it is. putting random numbers into it doesnt really make any sense, because you lose orientation in your pagination.
