React hook is called in a function which is neither a React function or a custom React Hook
React Hook "useState" is called in function "컴포넌트 이름" that is neither a React function component nor a custom React Hook function. React component names must start with an uppercase letter react-hooks/rules-of-hooks
export하는 컴포넌트의 첫 글자를 대문자로 바꿔주면 해결 됩니다.
function abc(
);
export default abc
->
function Abc(
);
export default Abc
해결!
