toList method
Creates a List containing the elements of this Iterable.
The elements are in iteration order.
The list is fixed-length if growable
is false.
Implementation
List<E> toList({bool growable: true}) {
List<E> result = growable ? (<E>[]..length = length) : new List<E>(length);
int i = 0;
for (E element in this) result[i++] = element;
return result;
}
