Provides a structured, configurable pipeline for scanning local audio tracks from MediaStore and SAF URIs. Implements filtering by minimum duration, hidden file exclusion, whitelisted folders, and SAF track deduplication. Returns a sorted list of CuteTrack objects. This is isolated (no imports of other internal modules beyond data models) and could be extracted as a reusable media scanning utility for any Android music app.

Parses synced lyrics from LRC files and embedded lyrics using EnhancedLrcParser and AutoParser from accompanist-lyrics. Handles timing tags, metadata headers, and plain text. The parsing logic is self-contained and could be reused in any application requiring LRC lyric support, with minimal adaptation.

A clean, type-safe wrapper around Jetpack DataStore for managing user preferences. Defines preference keys as top-level properties with default values and serializers, then exposes them as Flow properties in a single class. This pattern is reusable across any Android app that needs structured preference management with minimal boilerplate.

A utility extension function for combining up to 6 flows into one combined flow without nesting. This is a clean, reusable pattern for multi-flow aggregation, often needed in reactive UI layers. The implementation is generic and dependency-free, making it easy to extract into any Kotlin project.

A Compose dialog that handles track deletion with a system confirmation intent (using StartIntentSenderForResult). It manages deletion of multiple items, shows progress, and respects SAF vs MediaStore deletion paths. This is a reusable pattern for any Android app that needs to delete files with user confirmation, handling the complexity of different storage backends.
