Modal selector is opened after big delay, on iPhone5s delay is longer then on iPhoneX for e.g. But anyway, even on IphoneX it's taking too long.

This is also reported in issue #45 , and as I mentioned back then, the ScrollView may be replaced by FlatList. We are actively merging PR's, do you have the time to test if FlatList would fix the performance problem, and eventually make PR? It is of course fine if you got other suggestions than FlatList :-)

Any finding on this? I facing the same where the modal is too slow to pop up, don't have time to do testing with code changes though. If anyone experienced with this and came up with solution do share. Thanks a lot, I still prefer this modal selector.
