MvvmCross: how to go to something other than ViewModel?

Question

What would I add to my MvxCommand to go to a simple URL? All mobile platforms have a mechanism to ask the OS for an Activity or ViewController that can display the contents of a URL. How do I do this with MvvmCross? One of the ways I know about is to add special things to the presentationBundle and / or parameterBundle file when calling ShowViewModel, which the host can detect to execute the special OpenUrl command. But is this the best way?

There is a plugin that allows this - https://github.com/slodge/MvvmCross/tree/v3/Plugins/Cirrious/WebBrowser

If these plugins are loaded, then the view model can use:

public class MyViewModel : MvxViewModel { private readonly IMvxWebBrowserTask _webBrowser; public MyViewModel(IMvxWebBrowserTask webBrowser) { _webBrowser = webBrowse; } public ICommand ShowWebPage { get { return new MvxCommand(() => _webBrowser.ShowWebPage("https://github.com/slodge/mvvmcross"); } } 

You can see how it is used, for example:

• https://github.com/slodge/MvvmCross-Tutorials/blob/master/Sample%20-%20CirriousConference/Cirrious.Conference.Core/ViewModels/BaseViewModel.cs
• https://github.com/slodge/MvvmCross-Tutorials/blob/master/Sample%20-%20CustomerManagement/CustomerManagement/CustomerManagement/ViewModels/DetailsCustomerViewModel.cs
