How to determine location of a tap in Xamarin Forms?

Question

In Xamarin Forms how do I find out the location of a tap (within an image, say)?My code is:

var tapGestureRecognizer = new TapGestureRecognizer();
tapGestureRecognizer.Tapped += OnTapGestureRecognizerTapped;
image.GestureRecognizers.Add(tapGestureRecognizer);
...
...
void OnTapGestureRecognizerTapped(object sender, EventArgs args)
{ ... }

args.Parameter returns null (for iOS). I did not find any docs for Parameter. In the handler I tried changing EventArgs to TappedEventArgs but then did not compile. Also tried casting args to TappedEventArgs but that did not change anything.

At the moment of writing this answer it seems that there is no way of receiving the coordinates of the tap in XamarinForms without platform specific code. There are third party libraries (mentioned here) which provide this information.
