getLegacyStats method
Temporarily exposes _getStats and old getStats as getLegacyStats until Chrome fully supports new getStats API.
Implementation
Future<RtcStatsResponse> getLegacyStats([MediaStreamTrack selector]) {
var completer = new Completer<RtcStatsResponse>();
_getStats((value) {
completer.complete(value);
}, selector);
return completer.future;
}
