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> list;
if (growable) {
list = <E>[]..length = length;
} else {
list = List<E>(length);
}
_writeToList(list);
return list;
}
