@easyhooon 로그인 API 에러 처리 방식을 개선하면서 LoginSideEffect를 초기화해주는 로직이 필요해졌습니다. (안그러면 카카오 로그인 재시도 시 무한로딩 발생) 토스트메세지 이벤트처럼 UUID 값을 사용하는 방식으로 변경했는데 확인 부탁드립니다

아 무한로딩 발생하는게 이거 때문이었군여
분명 타임아웃 시간이 지나서 로딩이 끝날때가 되었는데 계속 돌길래 뭔가했는데

        fun handleEvent(event: LoginUiEvent) {
            when (event) {
                is LoginUiEvent.OnKakaoLoginButtonClick -> {

                    sideEffect = LoginSideEffect.KakaoLogin()
                }
  1. 사용자가 카카오 로그인 버튼 클릭
  2. sideEffect = LoginSideEffect.KakaoLogin() → RememberedEffect 실행
  3. 카카오 로그인 실패 → eventSink(LoginUiEvent.LoginFailure(...))
  4. sideEffect = LoginSideEffect.ShowToast(...) → RememberedEffect 실행 (Toast 표시)
  5. 사용자가 다시 카카오 로그인 버튼 클릭
  6. sideEffect = LoginSideEffect.KakaoLogin()
    -> 문제:프로퍼티가 없는 LoginSideEffect.KakaoLogin()은 구조적으로 동일한 값으로 인식됨
  7. Compose가 state.sideEffect가 변경되지 않았다고 판단
  8. RememberedEffect가 재실행되지 않음
  9. 카카오 로그인이 다시 시작되지 않음
  10. isLoading = true만 남아 무한 로딩

uuid 방식으로 해결할 수 있는 케이스라 괜찮은거같습니다!
