Throws permission denied error when calling SerialPort.availablePorts method on Android. I have tried adding the intent filer and meta data fields as per Android USB Host but it still throws the same error.

I had exactly the same error
I'm also Facing this same error.
If Anyone have solution for this error.pls replay..

I had this problem in the emulator and I did not have such a problem in the real device.
For cross-platform purposes, I recommend the "usb_serial" lib for Android, which works, while the "Libserialport" doesn't work.
Have this problem as well, anyone have any updates?
i also have the same problem in arm64
You could try using usb_serial plugin instead, I got that one working by using the latest commit from Github instead of the release on pub.dev. See my comment on a similar question: https://github.com/jpnurmi/flutter_libserialport/issues/76#issuecomment-1609026132
We put permission handling in todo.
