실습8 - PageController 사용해보기에서 질문 있습니다.
// 이미지 자동으로 다음페이지로 이동
controller.animateToPage(
nextPage,
duration: const Duration(microseconds: 400),
curve: Curves.linear,
);위 부분에서 Curves.linear로 했는데 애니메이션이 적용이안됩니다.
화면이 드래그되는 애니메이션으로 강의처럼 부드럽게 넘어가는것이아니라, 다음사진으로 뚝뚝끊겨 이동합니다...! 제가잘못한 부분이 어딘지,왜이런건지 혹시 알려주실수있을까요?
감사합니다.

안녕하세요!
지금 코드상으로 봤을때는 큰 문제가 없어 보입니다.
혹시 에뮬레이터/시뮬레이터에서만 그러는걸가요?
컴퓨터 퍼포먼스가 부족할때 말씀하신 현상이 나타날 수 있습니다.
실제 기기를 연결해서 확인해보시면 가장 정확합니다.
그게 아니라면 다시한번 댓글 부탁드립니다.
감사합니다!
보내주신 프로젝트가 아예 실행이 안되는데 확인 한번 부탁드립니다.

안녕하세요 에뮬레이터에서도, 그리고 실제 기기를 연결했을 때도 뚝뚝 끊기네요ㅠ. 컴퓨터 퍼포먼스가 부족한 경우엔 실제 기기 연동을 했을시에도 이 현상이 나타나는건가요? 이를 해결하려면 그럼 별다른 방법이 없을까요?
