[1,2,3,4,5,6]  이걸 다 합치면 몇이 될까?

 

for 를 쓰면 쉽게 되겠지

 

코드가 너무 길  것 같아서 줄일 수 있는 방법을 찾아보았다.

What is the cleanest way to get the sum of numbers in a collection/list in Dart?

I don't like using an indexed array for no reason other than I think it looks ugly. Is there a clean way to sum with an anonymous function? Is it possible to do it without using any outside variables?

.sum 을 사용하려면

import 'package:collection/collection.dart';

를 해줘야함
