https://github.com/peacechen/react-native-modal-selector

const [choices, setChoices] = useState<string[]>(["test"]);
const [choicesAnswer, setChoicesAnswer] = useState<string>("");

<ModalSelector
    data={[...choices.map((e, i) => ({ key: i, label: e }))]}
    initValue="정답지 선택"
    cancelText="취소"
    onChange={(option)=>{ setChoicesAnswer(option.label); }}
/>

이상하게 choices가 추가된 다음,, Selector onChange에서 setState를 시키면 랜더링 버그가 있는 것 같다.

💡대안

그냥 스크롤 핀을 사용하도록 하자..

const [choices, setChoices] = useState<string[]>(["test"]);
const [selectedLanguage, setSelectedLanguage] = useState();
<Picker
    selectedValue={selectedLanguage}
    onValueChange={itemValue => setSelectedLanguage(itemValue)}>
    {choices.map((choice, idx) => <Picker.Item key={idx} label={`${choice}`} value={choice}/>)}
</Picker>
