How to intercept WebView Navigating event in ViewModel

Question

My app has a WebView for displaying some contact information. It has a link to a website that I want to load externally using Device.OpenUri(). I\'m using FreshMvvm

Having revisited this recently for another project I stumbled across the answer. The updated XAML is:

The code in the ViewModel, that matches the tapped url against a list of valid options before opening the link in the device's browser, is:

public Command NavigatingCommand
{
    get
    {
        return navigatingCommand ?? (navigatingCommand = new Command(
            (param) =>
            {
                if (param != null && -1 < Array.IndexOf(_uris, param.Url))
                {
                    Device.OpenUri(new Uri(param.Url));
                    param.Cancel = true;
                }
            },
            (param) => true
            ));
    }
}
