Description

I have react picker drop down, its data source is constant object which is multlangual.
mean its labels property change if language changes on fly, but its index (value) wich is record it it remain same.

But i found react native picker loose its last state when we switch language,
it drop previously selected value and start again from default value if i change language from English to esponial.

It should not happen, because if Index is same,picker should not care about changing labels from english to spanish, i loose pickers value if switch language in middle of form.

Reproducible Demo

This is my dropdown data source which switch label if locale changed
var COUNTRY_RENDER = []; this.state.countryDropdown.map(function (item, index) { COUNTRY_RENDER.push({ label: (locale == "en") ? item.name : item.name_es, value: item.id }); });
