DataUtils

static List<String> ListPathsToUrls(List paths){
  return paths.map((e) => pathToUrl(e)).toList();
}

수정 후 아래와 같은 에러가 나서요..(Rating contents가 나오질 않습니다.)

==>

flutter pub run build_runner build로 해도 에러코드가 발생하는데.. 확인 부탁드립니다.

다음 강의 수강을 위해서 앱실행이 안되고 수업을 따라갈수가 없어서요.. 다시 한번 부탁드립니다.

lib/common/data_utils.dart:10:43: Error: A value of type 'List<dynamic>' can't be returned from a function with return type 'List<String>'.

- 'List' is from 'dart:core'.

return paths.map((e) => pathToUrl(e)).toList();

 ==> flutter clean
==> flutter pub get
==> flutter pub run build_runner build
===========> pub finished with exit code 78

flutter: type 'List<dynamic>' is not a subtype of type 'List<String>'
