Thank for reporting, there's a related issue https://github.com/AgoraIO/Agora-Flutter-SDK/issues/634, but should be fixed in 5.1.0, can you try flutter clean, and rebuild the APP to see if still has the same issue.

[Rohithgilla12]

Yes, I have cleaned cached in CI/CD pipeline and published it to stores

:(

[littleGnAl]

It's so weird that AgoraRtcChannelPlugin no longer has the dealloc implementation, seems the code does not match.

[littleGnAl]

Can you share the pubspec.yaml and the Podfile of the iOS module?

[Rohithgilla12]

@littleGnAl For the particular iOS module, can't share it since the build machine gets destroyed after building.

Do you want me to build it locally and share it?

I think the Podfile of iOS module resides inside the ios folder right?

[littleGnAl]

Yes, I'm not sure is there something that went wrong with the configuration.

[Rohithgilla12]

Not sure about what configuration But the app was live and working without issues for almost 5-6 months

Once the update happen this is creating issues 😔

[littleGnAl]

I will add more test cases to see if it can reproducible or not.

[albaschez]

Happening with flutter 3.0.5 and versions 5.2 and 5.3. When using joingCall the app just crashes, no trace

[littleGnAl]

Maybe relative https://github.com/AgoraIO/Agora-Flutter-SDK/issues/700

[Rohithgilla12]

As a temp workaround we have removed it from my application :(

[tselmeggkh]

Have you found any solutions for this?

[littleGnAl]

If you still face issues, please try upgrading to the new version to see if it works for you.
