sendStreamed method

Implementation

Future<void> sendStreamed(Response other) async {
  try {

    raw.statusCode = other.raw.statusCode;

    // Copy headers

      raw.headers.remove(key, values); // Remove any default
      for (var value in values) {
        raw.headers.add(key, value);
      }
    });

    // Stream the body from other
    // Since HttpResponse doesn't let you re-read the stream,
    // we'll assume the other Response has its content in memory
    // We'll use raw.addStream if possible
    // Otherwise, fallback to writing the body directly
    if (other.isClosed) {
      // Fallback: cannot re-stream, use raw content if stored
      raw.write(''); // Or store body in Response class if needed
    }
