operator []= method

@override void operator []=(int index, T 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, T value) {
  if (index >= length || index < 0) {
    throw ArgumentError('Illegal index');
  }
  index = (index + _first) % _store.length;
  _store[index] = value;
}
