Trigger native view events from Xamarin forms

I have created a HybridWebView according to https://developer.xamarin.com/guides/xamarin-forms/application-fundamentals/custom-renderer/hybridwebview/ and created a native ios WKWebView. Now I want to add custom controls to go Back/Forward/Home in Forms but I am not sure what is the recommended way to make a call from my Xamarin forms view into my native view to for example trigger the GoBack() of the ios WKWebView browser?

Should I try to call into my native implementation or should the native view listen to events from the forms view?

You would need to use the Xamarin MessagingCenter functionalities. It follows the publish-subscribe pattern. What you can do is publish a message in your Xamarin PCL and from your native projects you will have to subscribe to these published messages that comes from a Xamarin PCL trigger/event.

Sample code:

In your PCL you will have something like this:

 MessagingCenter.Subscribe<MainPage> (this, "Hi", (sender) => {
     // do something whenever the "Hi" message is sent
 });

And in your native project something like this:

 MessagingCenter.Send<MainPage> (this, "Hi");
