Process Management

Each service runs in an isolated Process.start() instance. This prevents a crash in one subsystem (e.g., Audio) from affecting others (e.g., Screen Mirroring).

State Broadcasting

A central ValueNotifier emits real-time state changes for UI updates across the application.

StateNotifier<Map<String, bool>>

Resource Cleanup

Strict exitCode listeners ensure PID termination and resource release when services are toggled off.
