Steps to reproduce

I'm using geolocator version

geolocator: ^10.1.0

on Android 11

i'm trying to stream out the position with

positionStream = Geolocator
.getPositionStream(locationSettings: locationSettings)
.listen( (Position? position) {

  if ( position == null ) {
    logger.info("getPositionStream: null");     
  }
  else {
    logger.info("getPositionStream: ${position.latitude.toString()}, ${position.longitude.toString()} ${position.altitude.toString} ");
  }
  
  if ( onPositionChange != null ) {
    onPositionChange(position);
  }

});

with configuration as follow

locationSettings = AndroidSettings(
accuracy: LocationAccuracy.high,
distanceFilter = 5,
intervalDuration = Duration(seconds: 5),
forceLocationManager: true,
intervalDuration: intervalDuration,
useMSLAltitude: true,
);

Expected results

I was expecting a valorized altitude with longitude and latitude.

Actual results

Altitude still ever setted up at 0.

What is worng?

thank you, i'm waiting for the flutter module update at the upper version ...

[Wackymax]

It won't update there. Running 'flutter pub upgrade' will pull the updated Android dependencyOn 29 Jan 2024, at 12:27, Andrea ***@***.***> wrote: than you i'm waiting for the flutter module update at the upper version ... —Reply to this email directly, view it on GitHub, or unsubscribe.You are receiving this because you commented.Message ID: ***@***.***>
