Facing the same problem, did you find a fix? @vonam2991

Same issue, device vid=6790, pid=29987 (CH340).

I was able to get the example code from this repo to work fine with this device, but copying and pasting the main.dart into a new flutter project (using flutter create with flutter version 3.13.0) has the same issue.

I think this points to an issue with the android specific code/configuration, but haven't tracked it down further.

Hmm as hinted at in #70 and a bunch of other issues in this repo, changing from targetSdkVersion 33 to 30 fixed this for me.

Maintainers of this lib should consider closing some of these as duplicates...
