Default Map Positon #667

Closed davidbuckleyni closed 4 years ago

davidbuckleyni commented 4 years ago

For the life of me I can't see how I set up the default map position when the map firsts start up or does it go to the first marker position.

I need the map to open at the user's current position. So what I do is get the current position using Xamarin Essentials GeoLocation. I then use the MoveToRegion method of the map, e.g:

map.MoveToRegion(MapSpan.FromCenterAndRadius(new Position(YOURLATITUDEHERE, YOURLONGITUDEHERE), Distance.FromMeters(1000)), false);

Not sure if there's a better way, but this works for me.

map.MoveToRegion is deprecated.

You can use map.InitialCameraUpdate property in you Page's constructor or XAML.
