Google Maps SDK

there is a package AutoFac - responsible for creating all the components of the application
there is a package Cirrious.FluentLayouts.Touch - is responsible for the automatic location (of the type of automatic display) of all displayed components
there is a package Google.Maps

this link leads to a issue with a marker - the marker is drawn higher than needed

When creating a Google Map Controller, and then when using it as a child controller, the marker is drawn incorrectly. And more specifically, then:

1) create a controller (parent)

2) this controller has a view with frame with an upper indent of 64 (any value)

`View.frame = ((0, 64), (width, height))`

3) create a controller with google maps

4) create mapview

`mapView = new MapView(new CGRect(0, 0, parentView.Frame.Width, parentView.Frame.Height))`

5) add a controller with google maps to the parent


6) add a view of google maps to the parent controller



7) inside the controller with google maps initiate display a marker


var mapCenter = new CGPoint(mapView.Center.X, mapView.Center.Y);

var mapCenterCoordinate = mapView.Projection.CoordinateForPoint(mapCenter);

var googleMarker = new Marker()


Title = "title",

Snippet = "someText",

Position = mapCenterCoordinate,

Icon = ...someImage,

Tappable = true,

Map = mapView



8) the marker is displayed incorrectly (empirically found that the readout of the Y coordinate comes from 0 and not from 64 as expected)

When creating a mapview with a frame with an upper indent of 64, the marker is drawn correctly, but then inside the map delegate the position definition is shifted along the Y axis by the same 64 points.

An example application that demonstrates the unexpected behavior of the marker is prepared. Thank.
