add method

@override void add(T element)

Adds value to the end of this list, extending the length by one.

The list must be growable.

final numbers = <int>[1, 2, 3];
numbers.add(4);
print(numbers); // [1, 2, 3, 4]

Implementation

@override
void add(T element) {
  if (_checkSize && _items.length > _size) {
   _reverse == true ? _items.removeLast(): _items.removeAt(0);
  }
  if (_reverse) {
    _items.insert(0, element);
  } else {
    _items.add(element);
  }
}
