Steps to reproduce

1. Add on gpx file while running the app in ios
   2.Initiate navigator session
   3.Location is not updating properly

Expected vs Actual Behavior

User location is not updating in navigator

Code Sample

 Future<void> startGuidance(
      {required LatLng origin, required Destinations destination}) async {
    try {
      await GoogleMapsNavigator.initializeNavigationSession();
      await GoogleMapsNavigator.simulator.setUserLocation(
        origin,
      );
      final NavigationRouteStatus status =
          await GoogleMapsNavigator.setDestinations(destination);

      if (status == NavigationRouteStatus.statusOk) {
        await navigationViewController?.setNavigationUIEnabled(true);
        await navigationViewController?.showRouteOverview();
        navigationTimeAndDistance =
            await GoogleMapsNavigator.getCurrentTimeAndDistance();
      }
    } catch (e) {

      rethrow;
    }
  }

@madhura13101998 Thanks for reporting this. Could you tell me first what is "gpx" and how are you using it here?

[madhura13101998]

@illuminati1911 We are using a GPX file to simulate device location during app development. This file contains GPS data including the starting point, destination, and the narrow route in between. By running the app in the Runner scheme on iOS, we can use this GPX file to mock the device’s location for testing purposes.

[illuminati1911]

@madhura13101998 Are you using this GPX file and its contents with the GoogleMapsNavigator.simulator.setUserLocation() function of our library or with some function of the background_locator_2 library or something else?

Generally if you want to mock the location of the user in the Google map, please use the setUserLocation() function of this library and avoid using other location libraries.

[madhura13101998]

The first image shows the navigation.gpx file, which mainly contains waypoints. In the second image, we’re using this file within the Runner scheme while running the app. This setup allows the simulator to mock the device’s location, simulating movement from the start point to the endpoint along the defined waypoints.
We’re not manually triggering navigation using the navigation SDK.

The scenario I’m trying to test is:
When the user's location changes in real time, will the navigation SDK automatically pick up those updates during turn-by-turn navigation, or do we need to push location updates to the SDK manually?
