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() {
  assert(ChangesNotifierHelperMixin.debugAssertNotDisposed(this));
  if (_list.isNotEmpty) {
    final List<T> removed = List<T>.from(_list);
    _list.clear();
    notifyListeners(ListChangeDetails<T>(const [], removed, 0));
  }
}
