Is distanceFilter working for AppleSettings?

## 💬 Questions and Help
I have initialized my Geolocator stream for iOS like this

```dart
if (defaultTargetPlatform == TargetPlatform.iOS ||
defaultTargetPlatform == TargetPlatform.macOS) {
locationSettings = AppleSettings(
accuracy: LocationAccuracy.high,
activityType: ActivityType.automotiveNavigation,
distanceFilter: 50,
pauseLocationUpdatesAutomatically: true,
// Only set to true if our app will be started up in the background.
showBackgroundLocationIndicator: false,
);
}

final positionStream = _geolocatorPlatform.getPositionStream(
locationSettings: locationSettings);
```

However, I seem to be receiving updates every second regardless of distance. This is an example of data received

For a 64 km drive, this resulted in 3586 updates with an average distance of 17.7 meters. The huge number of updates use processing time and power, and storage. I set my distanceFilter to 50 meters to prevent that many updates, but it seems to be not working. Is there a way to do that?

Start with the iOS AppleSettings configuration and the getPositionStream entry point, reproducing the reported distanceFilter: 50 behavior. Compare emitted updates with the configured threshold and document or test the expected filtering behavior; the issue is done when excessive updates are prevented or the platform limitation is clearly established.
