I'm using the sfMap and I need to find usre current location and allow to zoom on the map.

Hi Maryam, 
 
Greetings from Syncfusion. To find out the Current Geo location, we have to refer Xamarin.Essential package. After getting GeoCoordinate  location, we need to update this value to map markers to pin on the Maps. Please refer the below code snippet to get the GeoCoordinate points of current location. 
 
[C#]: 
private async void AddMarkerInCurrentLocation()
        {
            try
            {
                // To get the current location
                var location = await Geolocation.GetLastKnownLocationAsync();
               
                // Add the marker on the current location
                if (location != null)
                {
                    CustomMarker marker = new CustomMarker();
                    marker.Latitude = location.Latitude.ToString();
                    marker.Longitude = location.Longitude.ToString();
                    layer.Markers.Add(marker);
                }
            }
            catch (Exception ex)
            {
                // Handle not supported on device exception
                await Application.Current.MainPage.DisplayAlert("Alert", ex.Message, "Ok");
            }
        }
 
 
 
Please refer the below help document for adding Markers on Map.  
 
 
We have prepared a sample based on your requirement and it can be downloaded from the below link.
