Scroll Xamarin Forms listview when using bindings

Question

I am brand new to Xamarin and MVVM so this may be a stupid question.

I have a ListView which is populated using an observable collection, that collection is added to by a viewmodel.

What i want to do is when an item is added I want to scroll the listview to the bottom however the viewmodel does not have visibility to the listview control.

How can i get my listview to scroll when a new item is added to its collection?

I think you can use MessagingCenter.

In your ViewModel, when you Add the new Item you can MessagingCenter.Send a message, and in your Page you can subscribe to this message. When you receive this message in your Page, you can ScrollTo your ListView
