Picker Component resets when items list changes

Description

If the picker item list changes, then, in some cases, the picker will call the onValueChange callback with the first item in the list as it’s argument.

Reproduction Steps and Sample Code

This can be reproduced at https://snack.expo.io/Sy1JClEag.

Select 2 or 3, then click on exclude. The new value is 1. This does not happen if you select a higher value than the one being excluded

Solution

Do not call the onValueChange callback when the items list changes, but the selectedValue is stil present in the list

@stale This is still an issue.

@syamjayaraj’s link to a “solution” that is “working perfectly” has nothing to do with this issue. That solution refers to changing the selection of a Picker, not editing an Option for the Picker and having the current value reset after making that edit.

So, yes, this is still an issue in the react-native core and should remain on here and get some attention from the react-native team.
