[Flutter] ListView.builder


original
ListView 위젯은 작은 list에 사용하도록 만들어져 있다.

큰 리스트에서는 ListView.builder 를 이용하는 것이 좋다.

1. 데이터 만들기

final items = List<String>.generate(10000, (i) => "item $i")

2. 위젯과 데이터 결합 

ListView.builder(
  itemCount: items.length,
  itemBuilder: (context, index) {
    return ListTile(
      title: Text('${items[index]}'),
    );
  },
);
