Xamarin.forms.googlemaps: Add Map.InitialCameraUpdate property

[amay077]

FEATURE REQUEST / SUGGESTION

SUMMARY

Set maps initial location easily.

DETAILS

Now, initial location is Rome when page shown.
If change to other location then should call MoveToRegion in page constructor.

My suggestion is make Map.InitialCameraPosition as CameraPosition what is bindable property provides set initial location easily.

In code

class MyPage : Page {
  MyPage() {
    InitializeComponents();

    map.InitialCameraUpdate = CameraUpdateFactory.NewCameraPosition(new CameraPosition(
      new Position(34, 135),  // latlng
      14d, // zoom
      30d, // rotation
      60d)); // tilt
  }
}

In XAML

<maps:Map
    InitialCameraUpdate="34, 135, 14, 30, 60"   <-- direct setting by TypeConverter
    VerticalOptions="FillAndExpand" />

OR

<maps:Map
    InitialCameraUpdate="{Binding FirstCameraUpdate}"  <-- binding to ViewModel
    VerticalOptions="FillAndExpand" />

I am seeing the same error and I just updated to 2.1.0, if I remove the InitialCameraUpdate in Xaml the view no longer crashes.

[AbdelrahmanAA]

when i remove the camera from xaml it works

Thanks @kevincraig , @abdoelzamalkawy ,
Maybe I should change CameraUpdateConverter accessibility to public.

What about this problem ? Any solution ? I am getting Rome as the initial place and I need to initiate my map in my position, and not move from Rome to it... Everytime I start a new map, it shows Rome and after that, moves to my position.

Sorry guys, I still can't understand how this is possible.
It is exactly what I need too:

<maps:Map
    InitialCameraUpdate="{Binding FirstCameraUpdate}"  <-- binding to ViewModel
    VerticalOptions="FillAndExpand" />
