Issue with ProGuard in Flutter Jitsi Meet App

Problem Statement


I'm facing issues with JITSI in my Flutter app that integrates the Jitsi Meet SDK. The app is crashing or showing unexpected behavior during runtime, and I suspect it's related to ProGuard.

Details

• Flutter Version: [Your Flutter Version]
• Jitsi Meet SDK Version: [Your Jitsi Meet SDK Version]
• Error Messages or Logs: [Include any relevant error messages or logs]

What I've Tried


I have added ProGuard rules for Jitsi Meet SDK in my proguard-rules.pro file. Additionally, I've set minifyEnabled and useProguard to true in the build.gradle file.

class JitsiProvider extends ChangeNotifier {
bool _isMeetingComplete = false;
bool get isMeetingComplete => _isMeetingComplete;
bool _hasUserJoined = false;
bool get hasUserJoined => _hasUserJoined;
late Timer _meetingTimer;
void createMeeting({
required String appointmentID,
required String roomName,
required String meetURL,
required String meetDescription,
required bool isAudioMuted,
required bool isVideoMuted,
String username = '',
String email = '',
String userProfile = '',
bool preJoined = true,
bool isVideo = true,
bool isGroup = true,
}) async {
print("APP ID : $appointmentID");
try {
_hasUserJoined = true;
notifyListeners();

// Starting a timer for 15 minutes
// Initialize the meeting timer with a null check
_meetingTimer = Timer(
Duration(
minutes: 20,
), () {
callAPIappointmentCompleted(appointmentID);
endMeeting();
JitsiMeet().hangUp();
});
Map<String, dynamic> featureFlag = {};
featureFlag['welcomepage.enabled'] = false;
featureFlag['prejoinpage.enabled'] = preJoined;
featureFlag['add-people.enabled'] = isGroup;

var options = JitsiMeetConferenceOptions(
room: roomName,
serverURL: meetURL,
configOverrides: {
"startWithAudioMuted": isAudioMuted,
"startWithVideoMuted": isVideoMuted,
"subject": meetDescription,
},
userInfo: JitsiMeetUserInfo(
displayName: username,
email: email,
avatar: userProfile,
),
featureFlags: {
"unsaferoomwarning.enabled": false,
"add-people.enabled": false, // Set it to false here
'chat.enabled': true,
'invite.enabled': false,
'ios.recording.enabled': false,
'recording.enabled': false,
'kick-out.enabled': false,
},
);
var eventListeners = JitsiMeetEventListener(
conferenceTerminated: (url, error) {
print("MEET TERMINATED");
print(url);
callAPIappointmentCompleted(appointmentID);
},
participantLeft: (participantId) {
print("user has left");
print(participantId);
callAPIappointmentCompleted(appointmentID);
},
);
await JitsiMeet().join(options, eventListeners);
} catch (error) {
print("error: $error");
}
}

void onMeetingEnd() {
// Call your function here
callAPIappointmentCompleted("YOUR_APPOINTMENT_ID");
// Print the log message
print("Log out initiated");
}

void endMeeting() {
_isMeetingComplete = true;
notifyListeners();
_meetingTimer.cancel();
onMeetingEnd();
}




}

I tried to add this progaurd-rules.pro file-
