FormatException: Invalid radix-10 number (at character 4)

Hi. i am using your package and in the 0.5.2 version, everything was okay but in new update, the downloadStream has a bug, or maybe my code has an error but i can't get anything out of it.
This is my code:

Future<void> establishConnectionPure() async {
  try {
    FtpClient client2 = FtpClient(
        socketInitOptions: FtpSocketInitOptions(
            host: widget.ipAddress,
            port: 21,
            timeout: const Duration(seconds: 30),
            transferType: FtpTransferType.binary),
        authOptions:
            const FtpAuthOptions(username: "ftp", password: "123456"),
        logCallback: ((value) {
          print("Value:\n" + value);
          if (value.toString().contains("permission denied") ||
              value.toString().contains("Illegal Reply Exception")) {
            final snackbar = CustomSnackBar(
              mainAlignment: MainAxisAlignment.end,
              crossAlignment: CrossAxisAlignment.center,
              showCloseIcon: true,
              duration: const Duration(milliseconds: 2000),
              backgroundColor: Colors.red,
              widgets: [
                ReusableText(

              ],
            );
            ScaffoldMessenger.of(context).showSnackBar(snackbar);
            Future.delayed(

    file = client.fs.currentDirectory.getChildFile(path);
  }
  print("File got succesfully " + file.name);
  print("File got succesfully " + file.path);
  return file;
}

my scenario is to parse this callback log into lists inorder to build a better graphical interface.
"drwxr-xr-x 2 0 0 32768 May 15 2024 full_logs\r\n

-rwxr-xr-x 2 0 0 32768 May 10 2024 ENC.opus\r\n"

i will split each part into its own list. but when i want to download the file, i get this error:

E/flutter (32191): [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: FormatException: Invalid radix-10 number (at character 5)

and then timeout error.
