operator [] method

@override T operator [](int index)

The object at the given index in the list.

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

Implementation

@override
T operator [](int index) {
  if (index < 0 || index >= length) {
    throw RangeError.index(index, this);
  }
  return _buffer[(_head + index) % _capacity] as T;
}
