Build me a Flutter app for anime fans that lets people browse trending anime, explore a few categories, search for titles, and open a detail page for each show. On the detail screen, show the anime poster, summary, images, staff, characters, and any video or trailer if it’s available. I also want users to be able to save their favorite anime to a personal list and come back to it later, even after closing the app.

Keep the app feeling smooth and polished, with a nice animated bottom navigation, simple loading placeholders while data is coming in, and good error handling if the API is slow or something is missing. Use the Kitsu anime API for the data, and store bookmarks locally on the device. If you need to check current docs or best practices for Flutter packages, feel free to look them up online first.
