Xamarin.Forms.GoogleMaps iOS System.NullReferenceException

Question

The map is displayed properly with pins etc. However under iOS I'm receiving this error when switching to a different view, even without pins etc. Maybe a configuration issue in Info.plist?

我遇到了类似的问题，但是一旦我将xamarin.Forms.googlemaps更新到此版本https://www.nuget.org/packages/Xamarin.Forms.GoogleMaps/1.8.1
