React-Native Android ScrollView can't get event from onScroll

If there is only one item or few items in ScrollView on Android, I won't get any event from onScorll. In iOS, I still could get the event because the bounces.

My problem is how could I listen to the scroll offset on Android with a list? I've tried PanResponder, but in my case, I would like to detect the swipe down and up gesture in a vertical Flatlist.

In the end, I solved this problem by adding PanResponder for FlatList. When there are just few items, PanResponder works fine. On the other hand, if there are many items, I can get the nativeEvent from onScroll.

Flatlist is built internally using the responder API, so if it doesn't do exactly what you want then you definitely can use PanResponder.

If there is only a few items in your data array then the list can't scroll, so no scroll will be triggered.

If you are just trying to track a swipe gesture for example do dismiss something, that isn't really what Flatlist was designed to solve, and you could use PanResponder directly.
