Xamarin.Forms.Webview Crossplatform Geolocation, i

Question

I have a xamarin-forms-webview which refers to a webapp that uses geolocation. I know that in Android I need to override the method 'OnGeolocationPermissionsShowPrompt' as suggested here.

But I don't want to make the implementation for each platform. How can I enable the location in the xamarin webview?

I'm currently using this plugin to get de latitude and longitude.

Thanks.
