add method
- 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;
}
