operator []= method Null safety

  1. @override
void operator []=(
  1. int index,
  2. T value
)
override

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, T value) {
  _context.conditionallyRunInAction(() {
    final oldValue = _list[index];

    if (oldValue != value) {
      _list[index] = value;
      _notifyElementUpdate(index, value, oldValue);
    }
  }, _atom);
}
