API documentation and how to Send String instead of bytes? about flutter_libserialport HOT 2 CLOSED

1. Where are the API documentation? I see many in the issues section here writing commands and methods thart are not mentioned at all in this github

pub.dev -> API Reference.

2. How do I send strings via the serial port instead of sending bytes?

String.codeUnits

from flutter_libserialport.

pub.dev -> API Reference
I have been the above but the docs are minimal.
There is no tutorial on how to proceed further other than a listing of all serial ports.
It would be good if there are examples like configurations, reading of data and also some documentation on all the methods and data.

Thanks
