Performance issues

[andrekovac]

I'm experiencing some performance errors in the console of the react-native debugger of the kind '[Violation] 'message' handler took XXXms'
where XXX gets up to 767ms.

The FlatList I am using contains many images. The messages occur after I release at the bottom, i.e. when the onRelease callback is called.

Does anyone else experience these problems?

could you please give a demo repo that can reproduce this issue?

I am also experiencing serious issues with performance. Will see if there is an improvement on release. Im on 0.43

EDIT I swapped out the regular indicator for the custom indicator, and added useNativeDriver: true to the timing statements, and there is a drastic improvement. The layout is still all over the place though. Maybe add to readme how to recreate the demo in your gif?

@stokesbga Thanks for your reply and I will provide a example project about how to create custom indicator

Yes, I also noticed major performance issue when I try to wrap this with native-base components. List are not getting rendered properly
