clear method

@override void clear()

Removes all objects from this list; the length of the list becomes zero.

The list must be growable.

final numbers = <int>[1, 2, 3];
numbers.clear();
print(numbers.length); // 0
print(numbers); // []

Implementation

@override
void clear() {
  if (lock) return _internal.clear();
  if (isNotEmpty) {
    lock = true;
    added = const {};
    removed = super.asMap();
    changed = const {};
    _internal.clear();
    notifyListeners();
  }
}
