add method

@override void add(E value, { bool notifyListeners = true, })

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(E value, {bool notifyListeners = true}) {
  this.value.add(value);
  if (notifyListeners) {
    notifyAllListeners(
        CollectionEventType.addition, this.value.length - 1, value);
  }
}
