Steps to reproduce

Hi,

I'm running my appp on iOS 17.5.1 (real device)
(Precise Location in settings is ON, and all the relevant permissions in info.plist are there)

Using geolocator version 12.0.0

When try to get a location using "Geolocator.getCurrentPosition()"
(desiredAccuracy: LocationAccuracy.high but also with "best")

Somtimes it takes few seconds, sometimes few minutes, and sometimes it seems like it never ends.

What could be the reason and how can I solve this?
Is there any limitation in iOS or something?
(It was ok in the past)

(It happens also with "location' package, but there is it worst, it never completes)

Thanks

Expected results

Get a resopnse agter few secongs maximum.

@burekas7, I think I found something to make it works. Try this -
unawaited(Geolocator.getCurrentPosition());
await Geolocator.getPositionStream().first;

@ItayBarFaye thank you!

Version 13.0.2, Android

There seems to be a much older version of this post from 2020:
#559

I'd like to add some data; this problem occurs for our project, and I've collected some data on how often it happens. I am using @ItayBarFaye's fix and the bug continues to appear. It seems to be intermittent, yet consistent.

I am simply restarting my app with a 6 second timer. If the getPositionStream/getCurrentPosition succeeds by then, it logs a success. if it does not, it logs a failure. I can't seem to determine a cause; it's certainly not network connectivity.

I've chosen to mitigate this by simply using the cached version and updating the position with an unawaited call to the getPositionStream:

  Future<LatLng?> tryGetLocation() async {
    unawaited(Geolocator.getCurrentPosition());
    position = await Geolocator.getLastKnownPosition();
    if (position != null) {
      Geolocator.getPositionStream().first.then((value) {
        position = value;
      });
      return location;
    }
    else {
      position = await Geolocator.getPositionStream().first;
    }
    return location;
  }
