audioStats abstract method
Audio send/receive statistics, keyed by identity; key null = local.
Polled by the engine's stats timer alongside connectionQualities, and
the only route by which an audio bitrate reaches the app: without this,
nothing carries one back and setAudioProfile cannot be checked from
Dart at all. Empty until the media engine has produced a sample.
Implementation
Map<String?, VoxaAudioStats> audioStats();
