This is a fork from sunmi_printer and ideal sunmi_printer_pro, but i implemented a lot of other features described below #
Important: #
THIS PACKAGE WILL WORK ONLY IN ANDROID!
Support Sunmi and Null Safety.
I build this flutter plugin based on this:
Official Sunmi Inner Printer Doc. But not all method from doc was included in this package, beacuse i don't have equipment. If you have and can help me, just contact me on github!
