Implementation

factory MySQLPacket.decodeCommPrepareStmtResponsePacket(Uint8List buffer) {
  final header = decodePacketHeader(buffer);
  final offset = 4;
  final byteData = ByteData.sublistView(buffer);
  final type = byteData.getUint8(offset);

  late MySQLPacketPayload payload;
  if (type == 0x00) {
    payload = MySQLPacketStmtPrepareOK.decode(
      Uint8List.sublistView(buffer, offset),
    );
  } else if (type == 0xff) {
    payload = MySQLPacketError.decode(
      Uint8List.sublistView(buffer, offset),
    );
  } else {
    throw MySQLProtocolException(
      "Unexpected header type while decoding COM_STMT_PREPARE response: $header",
    );
  }

  return MySQLPacket(
    sequenceID: header.item2,
    payloadLength: header.item1,
    payload: payload,
  );
