Fixing Flutter Printing Issue

Job ID: 36710341

Budget: €8 – €30 EUR

I have a small Flutter App which is connected over WebSocket with a NodeJS Backend.
If a new Order is placed the Backend emits "new-order" Event with Order info as JSON.

This App Listens this Event and Parses this JSON and Prints. This App is installed on SUMNI V2 thermal printer.
It works fine but 2 small issues need to be FIXED

1: If I change the JSON Structure like add a new Field or change at some point the type it did not works. It should at least on adding new field should work without problem.
2: If the Web Socket is disconnected App auto reconnects the with Backend, I think then there is a problem the app starts to print the Info multiple Times. Not Sure why. Needs to be Search.


After Fixing this issue I need 2 new features which will be sepratly discussed but these issues need to be fixed.
The Code is really samll is just one single file which prints.

You should be really good at Flutter so the features should be implemented without any Issue.
