搜索返回0个结果时，不调用带有搜索的平面列表onEndReached

Question

I have a flatlist which fetch data from a remote server, the flatlist have pagination implemented and a linked search functionality. OnEndReached is called when I hit the end of the list and the next page is loaded, the same thing happen when I search through the list and one or more record is found that matchs the search criteria. However when I search through the list and there is 0 result matching the search from the already loaded records, in this case onEndReached is not called at all. I tried different value for the onendreachedthreshold but prop without success. Do you have any idea why is this happening. Thanks

Answer 1

onEndReached is called when the end of the view of the FlatList is within the range of the onEndReachedThreshold .

In the case where 0 results are displayed, the view of the FlatList would be within the visible screen area (ie no scrolling), hence, onEndReached won't be called. That's how onEndReached works.

PS If you're trying to display a message when 0 results are displayed, you should try calling it when the results are fetched and the page 1 is empty. Since I don't exactly know what you're trying to do, I can't suggest you the best solution. Try explaining a bit more maybe.
