Issues implementing the plugin in flutter

[Aagam9833]

I am trying to use the plugin in my flutter application. So to test it out I used the example code. The plugin has been able to recognize device name, VID, PID and other description. However when I tap on BulkTransferIn/Out it throws the following exception

What is the issue I don't understand. I would really appreciate if anyone can help me.

P.s : I am working on my company's custom device, and they have native java code with USBManager class wherein they can connect a custom device in charging port and read data from it. But now they wanna switch to flutter and I can't find any plugin which can help me with this issue. Any help in this regards is also highly appreciated

Line 141 in 57fdf0f

val actualLength = connection.bulkTransfer(endpoint, buffer, buffer.count(), timeout)

It seems to be buffer.count() throwing the exception. You'd better debug with internal Android SDK/logic code
