List<Movie> movies;
List<Widget> images;
List<String> keywords;
List<bool> likes;
int _currntPage = 0;
String _currntKeyword; <=여기는 파란줄
@override
void initState() {
super.initState();
movies = widget.movies;
images = movies.map((m) => Image.asset('./images/' + m.poster)).toList();
keywords = movies.map((m) => m.keyword).toList();
likes = movies.map((m) => m.like).toList();
_currntKeyword = keywords[0];
}
@override
Widget build(BuildContext context) {
return Container(
child: Column(
children: <Widget>[
Container(
padding: EdgeInsets.all(20),
),
