Also, when using onScroll, I receive this warning:

Warning: Don't set .props.onScroll of the React component <ScrollView />. Instead, specify the correct value when initially creating the element or use React.cloneElement to make a new element with updated props. The element was created by OrganizationProfileScreen.

Just based off of this

<ScrollView style={{backgroundColor: 'white', flex: 1, borderWidth: 0}} onScroll={this._onScroll}>
</ScrollView>

onScrollAnimationEnd doesn't seem to fire for horizontal scrolls

edit: need to use onMomentumScrollEnd - onScrollAnimationEnd refers to the incorrect event type and updating that does not fix it even

[brentvatne]

Might be useful to have a way to get the current contentOffset - just as we can access the contentSize

Note: this is a bit of a braindump right now from working with ScrollView, will cleanup when I'm done

👍 I posted these issues a few weeks ago while working on the calendar.
Was looking for confirmation that it wasn't working.

+1. I noticed other developers were using the following as well, which is not documented:

• onScrollBeginDrag
• onMomentumScrollEnd

This is a bit of a blocker. Can we have an estimate of when this will be looked into and fix will be released.

@sheki @stereodenis - you can upvote this on ProductPains - https://productpains.com/post/react-native/improve-scrollview-documentation/ - or if you are up for it, it would be great for you to have you look into the props and add some documentation yourself :)

After one year, onMomentumScrollEnd is still undocumented. Thanks for your investigations.

Thanks for onMomentumScrollEnd, ran into the same issue

[lesniakania]

I had the same issue. Thanks for this thread!

[pcottle]

onMomentumScrollEnd was a life saver, this should really get added to the docs! Glad Google indexed this thread :)
