Teaches how to add flutter_soloud to a Flutter app, configure each platform (web script tag and COOP/COEP headers, Linux audio backends ALSA/PulseAudio/JACK, Android/iOS/macOS minimum versions), initialize and deinitialize the engine, shrink binaries by excluding the Xiph libs, set up logging, and enumerate/switch output devices or Linux audio backends. Use when a user asks to install flutter_soloud, initialize SoLoud, set up web/background-audio prerequisites, configure Linux audio backends, reduce binary size, or switch the audio output device.
