지금은 하나의 피드 카드만 떠있지만, 인스타 처럼 이 카드의 수가 10개, 100개로 늘어난다면 'LazyColumn'을 사용하는 편이 좋습니다.
일반 Column은 항목이 100개라면 화면에 보이지 않더라도 100개를 한꺼번에 다 그리지만 LazyColumn은 이름처럼 '게으르게' 작동해서, 지금 화면에 보이는 5~6개만 딱 그리고 나머지는 메모리에서 아낍니다.
- 여러 카드를 띄우려면 여러 PostData객체가 필요하니 PostData를 여러 개 담은 List를 먼저 만들고 (보통은 서버에서 가져올테지만 지금은 데이터가 없으니 임의로 만듭니다)
- LazyColumn 내부에서
items(리스트)를 호출해서 리스트 개수만큼 FeedCard를 반복 생성
이런 방향으로 직접 구현해봐도 좋을 것 같습니다!
