operator []= method

@override void operator []=(int index, E value)

Sets the value at the given index in the list to value.

The index must be a valid index of this list, which means that index must be non-negative and less than length.

Implementation

@override
void operator []=(int index, E value) {
  if (_values[index] != value) {
    // Add/remove listener callback
    if (_propagateNotification) {
      if (_values[index] != null && _values[index] is ChangeNotifier)
        (_values[index] as ChangeNotifier).removeListener(_propagate);

      if (value != null && value is ChangeNotifier)
        value.addListener(_propagate);
    }
    _values[index] = value;
    notifyListeners();
  }
}
