selectedValue={selectedLanguage}
onValueChange={(itemValue, itemIndex) =>
setSelectedLanguage(itemValue)

pickerRef.current.focus();
}

function close() {
pickerRef.current.blur();
}

return ref={pickerRef}
selectedValue={selectedLanguage}
onValueChange={(itemValue, itemIndex) =>
setSelectedLanguage(itemValue)
}>
