'Issues with Easy Geofencing in Flutter when i am trying to call the service more then one time
i am trying to check if the user in specific geofencing zone using the Easy geofencing package but every time i call the EasyGeofencing.startGeofenceService() and EasyGeofencing.getGeofenceStream() with new position ( pointedLatitude, pointedLongitude, radiusMeter) the service do not work and the console print "Parse value===> false" if any one know how i solve this problem please help me, i am stuck since a week.
this is my code
