포스터 이미지 삽입했는데 오류뜨네요..

Question

권태뽕님과 똑같이 클론 코딩했는데 에러가 뜨네요..ㅠ 구글링 해봤더니 indentation은 잘 되어있었고  터미널에 flutter clean 명령은 효과가 없었네요.. 어떤 문제때문에 발생하는 오류일까요?!

아마 이렇게 넣으면 이미지가 잘 나올 것입니다 참고 바랍니다   images = movies ?. map (( m ) => Image . asset ( '../images/' + m . poster )). toList ();

안녕하세요! 강의 들어주셔서 감사합니다:) 파이어베이스와 연동하기 전 예제의 경우 m.poster의 값에 이미지 이름만 들어가 있습니다..! 따라서 해당 실습에서는 'images/' + m.poster의 형태로 이미지를 불러오셔야 정상적으로 참조가 될 것 입니다. 더 깔끔히 코드를 작성했으면 헷갈리지 않으셨을텐데 미흡하게 하여 죄송합니다ㅠㅠ

따라치며 클론해본 CarouselImage 클래스 입니다. import 'package:carousel_slider/carousel_slider.dart' ; import 'package:flutter/material.dart' ; import 'package:netflix_clone_practice/model/movie_model.dart' ; class CarouselImage extends StatefulWidget { final List < Movie > movies; CarouselImage ({ this .movies}); @override _CarouselImageState createState () => _CarouselImageState (); } class _CarouselImageState extends State < CarouselImage > { List < Movie > movies; List < Widget > images; List < String > keywords; List < bool > likes; int _currentPage = 0 ; String _currentKeyword; @override void initState () { super . initState (); movies = widget.movies; // Q. 여기서 widget은 어디로부터 온 것일까? images = movies. map ((m) => Image . asset (m.poster)). toList (); keywords = movies. map ((m) => m.keyword). toList (); likes = movies. map ((m) => m.like). toList (); _currentKeyword = keywords[ 0 ]; } Widget build ( BuildContext context) { return Container ( child: Column ( children: < Widget >[ Container ( padding: EdgeInsets . all ( 20 ), ), CarouselSlider ( items: images, options: CarouselOptions ( onPageChanged: (index, reason) { setState (() { _currentPage = index; _currentKeyword = keywords[_currentPage]; }); }, ), ), Container ( padding: EdgeInsets . fromLTRB ( 0 , 10 , 0 , 3 ), child: Text ( _currentKeyword, style: TextStyle (fontSize: 11 ), ), ), Container ( child: Row ( mainAxisAlignment: MainAxisAlignment .spaceEvenly, children: < Widget >[ Container ( child: Column ( children: < Widget >[ likes[_currentPage] ?

뒷 강의까지 진행해보았는데 CircleSlider로는 정상적으로 이미지 출력이 되는데 CarouselImage에서 오류가 있는걸까요?..
