# add method

void add(

1. E element

)
override

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

    void add(E element) {
      // This implementation only works for lists which allow `null` as element.
      this[this.length++] = element;
    }
