No further position received from stream

[i-dentify]

🐛 Bug Report

With location permissions being set to "Accuracy: reduced" I only receive a position when starting the stream - but no further position.

Expected behavior

At least with lowest accuracy submitted via settings there should be a constant position stream.

Reproduction steps

Code, that starts the stream.

_positionStream = Geolocator.getPositionStream(
        locationSettings: _getLocationSettings()
    );
    _positionSubscription = _positionStream!.listen((Position? position) {
      if (position != null && state.status.isActive) {
        add(PositionTracked(
            delivery: delivery,
            position: position
        ));
      }
    }, onError: (error) async {
      try {
        if (state.status.isActive) {
          LocationPermission permissions = await _checkPermissions(
              openAppSettings: true
          );

          if (permissions == LocationPermission.always ||
              permissions == LocationPermission.whileInUse) {
            add(TrackingStopped());
            add(TrackingStarted());
          }
        } else {
          throw error;
        }
      }
      catch (_) {
        rethrow;
      }
    });

  LocationSettings _getLocationSettings() {
    if (Platform.isAndroid) {
      return AndroidSettings(
          accuracy: LocationAccuracy.best
      );
    } else if (Platform.isIOS) {
      return AppleSettings(
        accuracy: LocationAccuracy.best,
        pauseLocationUpdatesAutomatically: true,
        showBackgroundLocationIndicator: false,
      );
    } else {
      return const LocationSettings(
        accuracy: LocationAccuracy.high,
        distanceFilter: 100,
      );
    }
  }

I also tried setting the accuracy to a lower mode step by step. But even with lowest there is no further action on the stream. onError did not get hit. I also added a onDone for testing purpose. But that did not get hit either. The only received position was received within onData - so there was no extra call on something else.

Which version of the plugin are you using?

[i-dentify]

geolocator: ^9.0.2

On android, this will not work:

    final position = await Geolocator.getCurrentPosition(
      desiredAccuracy: LocationAccuracy.lowest,
      timeLimit: Duration(seconds: 20),
    );

This is our current workaround:

    final position = await Geolocator.getCurrentPosition(
      // On android .lowest does not work for some reason. Use low instead, or it will load forever.
      desiredAccuracy: Platform.isAndroid ? LocationAccuracy.low : LocationAccuracy.lowest,
      timeLimit: Duration(seconds: 20),
    );

Dear @i-dentify,Can you please post the output of flutter doctor -v? Therefore, I can reproduce this issue. And can you also add some detailed information on how you are testing this (e.g. simulator, real-device, indoor/outdoor, permissions granted)?

I am testing in iOS Simulator with "City run" as selected option. Permissions are set as "While in use" with precise location accuracy being disabled.
