[Pedometer 4.0.1 ] Unable to trigger listen practice when screen_off

[knight0zh]

Please complete the following information for each phone and/or emulator you're experiencing this bug on:

• Device: Huawei P40 Pro
• OS: HarmonyOS 3.0.0 [compileSdkVersion 33]

Describe the bug

Listen is often triggered when screen_on and I can get the number of steps. But once screen_off is no longer triggered.

To Reproduce

Observe the printed event.steps.

  void initPlatformState() async {
    if (!await Permission.activityRecognition.request().isGranted) {
      return;
    }

    _stepCountStream = Pedometer.stepCountStream;
    _stepCountStream.listen(onStepCount).onError(onStepCountError);

    if (!mounted) return;
  }

  onStepCount(StepCount event) {
    print(event.steps);
    sLogic.updateStep(event.steps);
  }

Expected behavior

I hope it can also be triggered in the screen_off state. Apps for obtaining step counts generally need to run in the background and be in the screenoff state.

Actual behavior

What did happen? Include stack traces and exception print-outs.
