Xamarin Forms Location with Full features

Hi I am trying to build one Application in Xamarin forms which has huge dependency on location services.

Using Xamarin.Essentials I am able to get the location, but in Android its give the last known location and sometime its not that much accurate.

Problem 1.

But I am not able to add Location Listener so that once user change location, I can get notified.

Problem 2. How to exactly know whether user has disabled Phone Location or App Location ?

Please guide me.. Thanks in advance

Problem #1

I don't know, but i think Xamarin.Essentials doesn't have Location Listener feature yet, might be wrong, but you can use this plugin from jamesmontemagno (also a main developer of Xamarin.Essentials), this plugin can track geolocation changes like this:

CrossGeolocator.Current.IsListening

Problem #2

Following the documentation here, you receive an exception for the following cases: permission was not granted or if the location is not enabled/supported

try
{
    var location = await Geolocation.GetLastKnownLocationAsync();

    if (location != null)
    {
        Console.WriteLine($"Latitude: {location.Latitude}, Longitude: {location.Longitude}, Altitude: {location.Altitude}");
    }
}
catch (FeatureNotSupportedException fnsEx)
{
    // Handle not supported on device exception
}
catch (FeatureNotEnabledException fneEx)
{
    // Handle not enabled on device exception
}
catch (PermissionException pEx)
{
    // Handle permission exception
}
catch (Exception ex)
{
    // Unable to get location
}
