Using getPositionStream (GeoLocator)

Hi,

I am working through changing from getCurrentLocation to getPositionStream. As I need continuous navigation it is the recommended solution as far as I can see. The code below compiles and works.

My issue is that this gives me a single location, even though I have opened a position stream, which will continue feeding results.

Does anyone know if I re-run the same custom action if this opens another position stream, or reuses the one that's already open? That is what I will try next, and just see how it impacts performance, but there are so many people here that I´m guessing someone knows 🙂

After I exit my navigation phase I know I need to close down the stream, but I haven´t made this custom action as yet.

  List<double> coordinates = [];

    LocationSettings locationSettings = AndroidSettings(

    );

  StreamSubscription _positionStream = Geolocator.getPositionStream(

  ).listen(
    (Position position) {
      coordinates.add(position.latitude);
      coordinates.add(position.longitude);
    },
  );

  // double latitude = position.latitude;
  // double longitude = position.longitude;
  // Return the latitude and longitude as a list of doubles
  return coordinates;
