I would like to thank the whole appybuilder team for the great platform they have created.
The development of the application lasted a lot, has all the main functions of a cash register.
The biggest problem was that the application for how it was composed needed to be all on one screen, and it is made up of 9700 blocks, but with some trick I succeeded.
The application prints on thermal printers, thanks to the extension of ESC / POS Simple Converter by @Daniel
If you have suggestions to give, they will be welcome
In the future I will try to integrate the English language, even if it is quite intuitive
