frostnova721/animestream — reverse-engineered prompt

I want a Flutter app called animestream that feels polished and easy to use on Android first, with Windows support if it is already practical from this codebase. The main goal is simple, let people stream anime, download episodes for offline watching, and connect their AniList account so watch progress and tracking stay in sync. Make the UI feel modern and anime focused, with a clean home screen, show details, episode list, video player, download management, and basic account or settings screens if needed.

Please wire up whatever content sources and APIs this project is meant to use, keep the app stable, and fix the obvious rough edges so streaming and downloading both work reliably. If there are env values or signing steps needed, set up sensible examples and make the build process straightforward. I should be able to run it locally, build an Android APK, and if supported, build a Windows version too. You can look up current docs online if you need to.
