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 < _buf.length) {
    return _buf[(_start + index) % _buf.length];
  }
  throw RangeError.index(index, this);
}
