Summary of ChangesHello @chunjaemin, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! 이 PR은 채팅 인터페이스를 위한 재사용 가능한 하단 스낵바 컴포넌트를 도입합니다. 이 컴포넌트는 범용적인 페이드 및 슬라이드 애니메이션 훅을 활용하여 다른 UI 요소에도 적용할 수 있도록 설계되었습니다. 특히 키보드 상호작용을 고려하여 동적인 레이아웃에 원활하게 통합될 수 있도록 스택 기반의 배치 방식을 채택했습니다.

Code Review
The pull request introduces a new BottomSnackbar component with fade and slide animations, along with a useFadeSlideVisibility hook to manage its visibility and animation. The implementation looks clean and well-structured, providing a reusable solution for snackbar-like UI elements. The README.md file is comprehensive and provides clear usage instructions and prop documentation. The useMemo hook in useFadeSlideVisibility is correctly used to memoize animatedStyle, preventing unnecessary re-renders. Overall, the changes enhance the UI capabilities with a well-designed and animated component.

The useMemo hook here is correctly used to memoize the animatedStyle object. This is a good practice as it prevents unnecessary re-creations of the style object on every render, which could lead to performance issues, especially with complex animations or frequent re-renders of the parent component. This aligns with the general rule of avoiding useMemo when it only returns a prop without any complex computation, as here it does involve computation (interpolation) and depends on progress and translateYFrom.

useMemowhen it only returns a prop without any complex computation, as it offers no performance benefit and adds unnecessary complexity.

useMemo로 애니메이션 객체 재생성을 막은 것이라 이대로 유지하도록 하겠습니다
요약
스낵바 말고도 팝업창과 같은 다른 UI에도 쓸 수 있으니 애니메이션 필요하신 분들은 가져다가 쓰셔도 좋을 것 같아요
참고사항
스낵바는 absolute로 Floating 하지 않고, stack방식으로 돔 요소 위에 쌓이도록 구현했습니다.
키보드 유무에 따라 스낵바의 위치도 같이 움직여야 한다는 점을 고려했을 때 absolute 보다 stack 방식이 동적인 움직임을 더 간편하게 조작할 수 있을 것 같아서 stack방식을 채용했습니다
바텀 스낵바는 widgets에 구현했습니다.
스낵바 visible 상태관리는 props로 받아서 on/off 되도록 최대한 간단하게 구현해놓았습니다.
상태관리를 할 수 있는 방법이 여러가지라 이부분은 은혜님이 사용하시기 편한 방법으로 바꿔서 사용하시면 될 것 같아요 당장에는 가장 직관적으로 사용할 수 있도록 했습니다!
