Could you please be a bit more specific what's not working?

Could you please be a bit more specific what's not working?

The content in the input box cannot be synchronized to the widget

[ABausG]

Did you update the code with a appgroup id registered to your Apple developer account?

Could you also post a screenshot of the Signing & Capabilities Section in Xcode to make sure the App Group is configured there as well. Plus the Flutter code where you setup the Widget and update the widget

Sorry, I misunderstood the iCloud containers in the app as app groups. It's normal now

How to implement the following code using objective-c?

UIApplication.shared.setMinimumBackgroundFetchInterval(TimeInterval(60*15))

    WorkmanagerPlugin.setPluginRegistrantCallback { registry in
        GeneratedPluginRegistrant.register(with: registry)
    }
