Build me a Flutter app for streaming movies and TV series that feels like a real app people would use every day. It should let users sign in with email or Google, browse a home screen with featured titles, search for movies, shows, and actors, open detail pages with posters and episode info, and save things to a watchlist.

The most important part is playback. I want the app to find stream links automatically from multiple sources, play them smoothly with HLS, show subtitles, let users pick quality, remember where they left off, and auto play the next episode with a short countdown. If a stream source fails, it should try other ones in the background.

Please also include profile settings, watch history, local notifications, and a simple TV friendly mode with D pad navigation if that fits. Use TMDB for metadata, Firebase for auth and user data, and keep the UI polished with a modern look. If you need current docs for Flutter or Firebase details, look them up online and keep iterating until it works.
