update method

MessageContainer? update({ required ODIDMessage message, required int receivedTimestamp, required MessageSource source, int? rssi, })

Returns new MessageContainer updated with message. Null is returned if update is refused, because it contains duplicate or corrupted data.

Implementation

  required ODIDMessage message,
  required int receivedTimestamp,
  required pigeon.MessageSource source,
  int? rssi,
