ConferenceRole validation problem when joining AudioCall

[pedrostick3]

Platform (use [x]) [x] Android [] iOS [] macOS [] Windows [] Web

Device info Manufacture: Google Model: Pixel 4 OS version: Android API 30

Describe the bug: When i enter in an audiocall ( CallType.AUDIO_CALL ) it apears a problem in line 457 that has conferenceRole = ConferenceRole.values.firstWhere((e) => e.toString() == 'ConferenceRole.' + displayRole); on file connectycube_sdk-2.5.1\lib\src\calls\signaling\janus_signaler.dart.

Steps to Reproduce:

1. Create a call session ConferenceClient.instance.createCallSession(userId, callType: CallType.AUDIO_CALL).
2. With Mobile1, Enter in AudioCall using method callSession.joinDialog().
3. With Mobile2, Enter in the same AudioCall using method callSession.joinDialog().
4. On Mobile1, Error appears refering a "Bad state: No element" in your library on file connectycube_sdk-2.5.1\lib\src\calls\signaling\janus_signaler.dart, line 457, method void eventParser(WsEvent wsEvent).

Actual result: Everytime i enter in audio call this bug comes up.

Expected behavior: Enter in audio call without problems.

Additional info I fixed it by going to this file connectycube_sdk-2.5.1\lib\src\calls\signaling\janus_signaler.dart in line 457 and change from this:

conferenceRole = ConferenceRole.values.firstWhere((e) => e.toString() == 'ConferenceRole.' + displayRole);

to this:

conferenceRole = ConferenceRole.values.firstWhere((e) => e.toString() == 'ConferenceRole.' + displayRole.toUpperCase());

Hope it helped :) Please fix this bug and contact me when you merge this into a new package version so i can update it ;)
