Implementation

  if (raw == null) {
    return Session.newSession({});
  }

  }
  final String sid = values['sid']!;

  if (!values.containsKey('sct')) {
    // TODO throw exception?
    return Session.newSession({});
  }
  final String timeStr = values['sct']!;
  final int? timeMilli = int.tryParse(timeStr);
  if (timeMilli == null) {

    return Session.newSession({});
  }
