[Flutter] location.onLocationChanged is calling even when i am not moving at all

Following Code shows that in a flutter widget I have used location.onLocationChanged listeners so that i can record some points while a person moves and later show them on the map as a path. but it is not working as soon as i come on this same page it starts to call continuously.Even when I am not moving.

@override
void initState() {
_progressHUD = new ProgressHUD(
backgroundColor: Colors.black12,
color: Colors.red,
containerColor: Colors.white,
borderRadius: 5.0,
loading: false,
text: 'Updating...',
);
setState(() {
isEnding = false;
});
checkLocation();
getCurrentRide();
location.changeSettings(accuracy: LocationAccuracy.high);
locationSubscription =
location.onLocationChanged.listen((LocationData currentLocation) {
// Use current location
if (currentRideId != null && !isEnding) {
final collRef = Firestore.instance.collection('rideLocations');
DocumentReference docReference = collRef.document();
docReference.setData({
"lat": currentLocation.latitude,
"long": currentLocation.longitude,
"time": new DateTime.now(),
"locationId": docReference.documentID,
"rideId": currentRideId,
}).then((doc) {
Timer(Duration(milliseconds: 150), () {
print("init location timer");
// Navigator.pop(context, true);
});
}).catchError((error) {
print(error);
});
}
print(
"currentLocation is --------------- ${currentLocation.latitude}${currentLocation.longitude}");
print("ongoing ref $currentRideId");
});
super.initState();
}
