Flutter usb serial with arduino, Not detecting CH340

Issue

I'm trying this package usb_serial to communicate with my hardware devices like Arduino, Esp8266, Esp32, FTDI board, etc.,

Right now I'm using a board with a CH340 chip in it. Device details are matching as mentioned in device_filter.xml

In device_filter.xml

Am I missing somthing here, please help me if you know. Thank you

Solution

I found the solution.
In the example code I commented subtitle: Text(device.manufacturerName!), line.
The reason is I was using an unbranded CH340 chip, which did not have the manufacturer's name on it.
