Proposal: Add Test Automation with Appium

[raulexacon]

Hi, I saw that the project is open to contributions, and I was wondering if it might be useful to add some Test Automation using Appium with Java. I noticed that the code is mostly written in Dart, but I’d still like to contribute by improving the automated testing part. Do you think this would be a useful direction for the project? Let me know if you think this could help!
