Coffee-Expert/Apple-Music-New-UI ? reverse-engineered prompt

Build me a Flutter app that feels like a fresh Apple Music clone, with a polished redesigned music player look and smooth, modern screens.

I want users to be able to browse a simple music library, open a track, and play audio that comes from files bundled in the app, not from an external service. The player should support the usual controls like play, pause, skip, previous, and shuffle, and it should feel responsive and easy to use. Make the interface look clean and close to Apple Music, but with its own style.

Please set it up so it runs nicely across the main platforms Flutter supports, and use the sample assets in the project for the demo experience. If you need to check current Flutter or audio package docs online while building it, go ahead.
