[Bug][SwipeableFlatList] First item not updated for the first time. Second, third... OK

[kesha-antonov]

Hello!

If you pass updated data to SwipeableFlatList for the first time - item at index 0 will not be updated. On second, third etc. item updated as expected.

Also if you pass updated data to SwipeableFlatList for the first time item at index higher than 0 they'll be updated as expected.

Some weird bug.

For now I just update data 2 times at one time just to be sure.

Is this a bug report?

Thanks for posting this! It looks like you may not be using the latest version of React Native, v0.53.0, released on January 2018. Can you make sure this issue can still be reproduced in the latest version?

I am going to close this, but please feel free to open a new issue if you are able to confirm that this is still a problem in v0.53.0 or newer.
