Sanaullah49/flutter_wallpaper_plus — reverse-engineered prompt

Build me a polished Flutter plugin called Flutter Wallpaper Plus for Android that lets app developers set wallpapers from images or videos.

It should support setting image wallpapers from an app asset, a local file, or a URL, with choices for home screen, lock screen, or both when the device allows it. Add an auto changing wallpaper playlist for images, where the app can schedule a list of wallpapers to rotate at an interval, check whether it’s running, stop it, and apply the next one right away.

Also support video live wallpapers by opening the Android live wallpaper chooser, including looping and optional audio. Include video thumbnail generation, cache size controls, clearing cache, and safe handling for large images. Return clear success or failure results with useful error codes instead of just throwing random errors.

Make an example Flutter app that demonstrates all the main actions with a simple clean UI. This is Android only, API 24 and up. Look up current Flutter and Android plugin docs if needed.
