## Description

Echo is a mobile music player designed for playing local audio files on mobile devices through a dedicated user interface. It functions as a local media indexer that scans and catalogs offline music files from device storage to build a searchable library.

The application uses a plugin-based architecture to extend functionality without modifying the core code. This system allows for dynamic plugin loading and runtime module injection from installed packages to add capabilities such as lyrics and music tracking.

The project incorporates a dynamic asset resolver to map external plugin resources to internal paths for rendering media and metadata. It also employs a centralized state-driven UI to synchronize the user interface with the playback engine.
