@override void close()

Closes the sink.

The add method must not be called after this method.

Calling this method more than once is allowed, but does nothing.

@override
void close() {
  if (_closed) {
    return;
  }
  _closed = true;
  _sink.add(brotliCompress(_input.takeBytes(), options: options));
  _sink.close();
}
