addAll method
Appends all objects of iterable
to the end of this list.
Extends the length of the list by the number of objects in iterable
.

final numbers = <int>[1, 2, 3];
numbers.addAll([4, 5, 6]);
print(numbers); // [1, 2, 3, 4, 5, 6]
Implementation
@override
void addAll(Iterable<E> iterable, {bool notifyListeners = true}) {
final startIndex = value.length;
value.addAll(iterable);
if (notifyListeners) {
_notifyEventListeners(CollectionEventType.addition, iterable, startIndex);
this.notifyListeners(value);
}
}
