Can Flutter SDK screen sharing reduce configuration items?

[quentin996007]

I am using Flutter SDK to implement the screen sharing feature, everything works fine in the development environment, when I re-sign the ipa file and then run the APP, once I start screen sharing it causes the APP to crash.
The reason for the crash is that I followed the documentation at 'https://getstream.io/video/docs/flutter/advanced/screen_sharing/', which says 'Finally, you should add a new entries in the Info.plist files. In both the app and the broadcast extension, add a key RTCAppGroupIdentifier with a value of the app group id and RTCScreenSharingExtension key with a value of a bundle id of your extension.'
When I remove the app group id, I don't get flashing due to re-signing the ipa. I just can't push the stream.
I've previously interfaced with other service providers, such as Tencent, and their documentation clearly states that you can push streams without configuring the app group id, and everything works fine after re-signing the ipa.
Reference: 'https://www.tencentcloud.com/document/product/647/37338?lang=en&pg='
My problem is as follows:
Why does re-signing cause the screen sharing function to flash back after configuring the app group id? Can I not configure this value? If this value doesn't affect the screen sharing feature even if I don't configure it, I think the problem is solved.
Thanks for your help, I hope you can check my problem and give me some help, thanks!

I think that if you don't want to configure App Group, you can only share the built-in UI screen of the APP. For the content of the entire iPhone system, you must configure App Group and Extension to share.

If you don't want to configure App Group, you can only share the built-in UI screen of the app. However, for the content of the entire iPhone system, you must configure App Group and Extension to share.

I found other solutions in other SDKs, which seem to use local socket implementation. For example, Tencent and Agora can perform screen sharing on the iOS platform without needing to configure App Groups.
