flutter – callbackDispatcher technique not responding whereas utilizing Workmanager().registerOneOffTask in IOS

I’m making an attempt to run workmanager package deal on IOS. It really works wonderful on android however would not work on IOS. I’m utilizing iphone 14 to check. I did setup for ios following iosSetup.
callbackDispatcher would not reply.

That is my key

    const simpleTaskKey = "be.tramckrijte.workmanagerExample.simpleTask";

That is the operate that’s not responding in any respect

 void callbackDispatcher() {
      Workmanager().executeTask((process, inputData) async {
      swap (process) {
        case simpleTaskKey:
          print("$simpleTaskKey was executed. inputData = $inputData");

          closing prefs = await SharedPreferences.getInstance();

          prefs.setBool("check", true);
          print("Bool from prefs: ${prefs.getBool("check")}");
       break;
 
         case Workmanager.iOSBackgroundTask:
         print("The iOS background fetch was triggered");
         Listing? tempDir = await getTemporaryDirectory();
         String? tempPath = tempDir.path;
         print(
           "You'll be able to entry different plugins within the background, for instance 
         Listing.getTemporaryDirectory(): $tempPath");
      break;
     }

    return Future.worth(true);
   });
 }

code that initializes workmanager

  ElevatedButton(
              youngster: Textual content("Begin the Flutter background service"),
              onPressed: () {
                Workmanager().initialize(
                  callbackDispatcher,
                  isInDebugMode: true,
                );
              },
            ),

code to set off reisterOneOffTask

         ElevatedButton(
              youngster: const Textual content("Register OneOff Job"),
              onPressed: () {
                Workmanager().registerOneOffTask(
                  simpleTaskKey,
                  simpleTaskKey,
                  inputData: <String, dynamic>{
                    'int': 1,
                    'bool': true,
                    'double': 1.0,
                    'string': 'string',
                    'array': [1, 2, 3],
                  },
                );
              },
            ),

    <string>be.tramckrijte.workmanagerExample.simpleTask</string>
