operator []= method Null safety

  1. @override
void operator []=(
  1. int index,
  2. Node 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, Node value) {
  if (value is DocumentFragment) {
    removeAt(index);
    insertAll(index, value.nodes);
  } else {
    this[index].parentNode = null;
    super[index] = _setParent(value);
  }
}
