Flutter health package is not returning real time data on ios,i have to reopen the app or have to switch between my app and ios health app for update

Question

I am calling health package in a timer each second but it is not updating the steps value fetched from ios health kit i have to either reopen the app or switch between ios health app and my app

Timer.periodic(const Duration(seconds: 1), (timer) async { todaySteps.value = await GoogleFitController.getSteps() ?? 0; });

static Future<int?> getSteps() async { HealthFactory health = HealthFactory(); int? steps;

var now = DateTime.now();

var midnight = DateTime(now.year, now.month, now.day, 0);
try {
  steps = await health.getTotalStepsInInterval(midnight, now);
} catch (e) {
  print("steps error ====== ${e.toString()}");
}
print("steps from google fit foreground ===== = == = = === $steps");
return steps;

}

it is working but not updating in real time all the permission has been granted
