uzibytes/Voco_App ? reverse-engineered prompt

Build me a Flutter app called VoCo for people with visual impairment that helps them learn vocational and language skills in a simple, voice friendly way.

I want the app to feel very accessible, with in app voice guidance, easy navigation, and a clean layout that works well with screen reading and spoken instructions. It should let users sign in, browse learning content, hear study material in audio form, and practice pronunciation in English. Add a section for quizzes or short tests so users can check progress, plus a feedback area so they can rate the content. I’d also like a basic chatbot style help feature, and a way for users to connect with experts or other learners later if possible.

Make it mobile first, polished, and ready to run on Android and web if you can. If you need to look up current Flutter or Firebase docs online, go ahead.
