Broken Example

[PhantomKnight287]

I cloned the repository and tried to run the application inside example folder. The app started but when I clicked on the button to start live activity, I get the error of null check used on a null value. Below is the image and stack trace of the error.

Thanks for raising an issue, I will check that ASAP

Hi, I tried on my side and I can't reproduce it. Maybe do you have a valid App Group registered? (check the following steps here : https://github.com/istornz/flutter_live_activities?tab=readme-ov-file#-native)

[PhantomKnight287]

Yes, I have a valid group id.

[istornz]

It seems the plugin can't access to your app group in this code :
Directory? sharedDirectory = await FlutterAppGroupDirectory.getAppGroupDirectory( appGroupId!, );

The sharedDirectory return null on your side, maybe an issue by configuring the app group? Do you have added AppGroup for both Runner and your widget extension?

[PhantomKnight287]

Yes it is configured for both Runner and Widget extension.

have you fixed this??
or a workaround?

No

[istornz]

Do you have correctly set the appgroupid for both Swift code and Dart?

let sharedDefault = UserDefaults(suiteName: "REPLACE_HERE")!

_liveActivitiesPlugin.init(
        appGroupId: 'REPLACE_HERE', urlScheme: 'la');
