flat-list-mvcp: Android Issue: Exception in native call from JS

This occurs on Android when changing FlatList data too rapidly

In addition to that there is a ref issue in the code - you assign an unnecessary ref and also block on the way the forwarded ref

<FlatList
        {...props}
        ref={(ref) => {
          // @ts-ignore
          flRef.current = ref;
          typeof forwardedRef === 'function' && forwardedRef(ref);
        }}
      />

I’ll submit a PR for the refs however, I still would like an insight on why it drops that error

Have published 0.0.9 with latest changes. Thanks once again 😃

I usually have 5-10 items in the list in the beginning, but with 0.0.9-dev.1 it seems to work most of the time (with the first one working every time). Around 80% of the times it works for me but once it even crashed with the same error if I scrolled very quickly in both directions. Haven’t been able to make it crash again though. For my usecase, this is probably good enough, but might not be for everyone.

EDIT: 80% might be around 90-95% instead, it is working quite well now.

@karri-lehtiranta @rgbedin So I was trying to mess around some logic, and this looks like a decent middle ground: https://github.com/GetStream/flat-list-mvcp/pull/11/files

I have published 0.0.9-dev.0 and seems to be working well. Could you give it a shot … and check if it works for your cases as well? 😃

Basically if you have some onScroll handler which makes a call to setState - then FlatList invokes ref callback, which results in call to resetMvcpIfNeeded. So I guess little debounce will do a trick here.

Thanks in advance

@rgbedin I am looking into in as I type this 😄
