get
Gets the statistics report from the OpenTok (Vonage) SDK from a virtual visit. A Virtual Visit must have been started in the current app session, and the Provider must have started the visit for this method to return any results.
These statistics are only stored in memory, and are cleared upon starting a new visit, calling DexCareSDK.signOut(), or by closing the app (since they're only in memory).
Return
null when a virtual visit conference has not been conducted during the current SDK session, otherwise a VideoCallStatistics object containing RTC and Network statistics about the last video conference that occurred within the current SDK session.
