Scroll view not bouncing back to proper position in LargeList V2

[preethi-pnrao]

Hi,

I have been using the LargeList v2 for quite some time, Amazing performance plus bounce animation on android is added benefit.

I just found one issue mainly on my android device(Samsung s8)
I have large list of data(more than 100 entry), when I scroll up and down the LargeList shifts its position leaving behind quite big space from top and hiding some rows in the bottom, this issue is preventing me from using this library. I tried disabling bounce still facing same issue. I could see same issue on the sample app given. It would be of great help if I get any inputs or alternatives from your side.

Reference for empty space at the top of the list

Reference for hiding some rows at the bottom(bouncing back to wrong position)

Regards
Preethi

This issue does exist on LargeList . It is mainly manifested on Android simulator. And it is much better on real Android Devices. I have never had this issue on iOS.

This issue often occurred when JavaScript thread is stuck. I want to make VerticalScrollView native, but no one helps me build Android native module.

You can use NativeLargeList instead now.

Hey I am android native developer, I can help you on this , let me know what am I supposed to do(though I have never connected react-native with android native module), so far this I found this largelist the best , so I would definitely like to help you on this.

And also this issue occurs more often if the renderItem (row object) is heavy if the component has many views in it, this issue occurs more often

I want an iOS style ScrollView include:

1. bouncing（pulling to refresh and loading more）
2. native onScroll event, same as ScrollView in react-native
3. both horizontal and vertical scroll
4. zoom scale with two fingers gesture.
5. more natural deceleration
6. more accurate events
7. scrollsToTop
8. initialized offset
9. scrollTo
10. resolve keyboard avoiding

I had did an Android native SpringScrollView. It is on the V2 branch of react-native-spring-scrollview

If you are free ,you can clone and test it. @datner @preethi-pnrao
