Steps to reproduce

Here's my onEndReached re-implementation to prevent the callback to be triggered even if the list is empty and to trigger it only once:

if (!endReached.current && dataSize > 0) {
  endReached.current = true;
  onEndReached?.();
}

And every time the data size changes, the endReached is set to false again:

useEffect(() => {
  endReached.current = false;
}, [dataSize]);

And then the list:

<FlatList onEndReachedThreshold={0.2} />

Now the problem arise when loading the list for the first time, the onEndReached callback is triggered even if the list is empty and once the list is populated, downloading items asynchronously, and reach the end the callback it's not triggered.

But if the list data area cached, the second time I load the list the onEndReached is not triggered at the beginning but on the right way.

It seems that the error, or I think the bug, arise when the list is empty because data are loading, indeed if I set a condition to render the list only after the data are fully loaded, the onEndReached is trigged correctly.

Tái hiện chuỗi tải lần đầu bằng cách sử dụng FlatList, onEndReachedThreshold={0.2} và dữ liệu được điền bất đồng bộ từ issue. So sánh với trường hợp dữ liệu được lưu trong bộ nhớ đệm và cách giải quyết bằng conditional rendering, sau đó lần theo entry point của onEndReached. Được xem là hoàn tất khi một danh sách ban đầu trống không thực thi callback trước khi dữ liệu đến, trong khi việc chạm đến cuối danh sách sau đó vẫn kích hoạt callback.
