ListView ItemSelected Issue

I am very new to Xamarin.Form, I would appreciate your help.

I am using MVVM pattern for my current project. I have listview populated with people, I want to select the item in list view and show the detail.

This is my Bindable Class
public static readonly BindableProperty CommandProperty =
BindableProperty.Create(
propertyName: "Command",
returnType: typeof(ICommand),
declaringType: typeof(ListViewItemSelected));

    public ICommand Command
    {
        get { return (ICommand)GetValue(CommandProperty); }
        set { SetValue(CommandProperty, value); }
    }

    protected override void OnAttachedTo(ListView bindable)
    {
        base.OnAttachedTo(bindable);

        bindable.ItemSelected += BindableOnItemSelected;
        bindable.BindingContextChanged += BindableOnBindingContextChanged;
    }

    private void BindableOnBindingContextChanged(object sender, EventArgs e)
    {
        var lv = sender as ListView;
        BindingContext = lv?.BindingContext;
    }

    private void BindableOnItemSelected(object sender, SelectedItemChangedEventArgs e)
    {
        //var lv = sender as ListView;
        //var vm = lv?.BindingContext as PersonsListViewModel;
        //vm.DetailViewCommand.Execute(null);

        if (Command == null)
            return;
        Command.Execute(null);
    }

I am not sure about the next step in my ViewModel.
I created ICommand Property to exacute the method

public ICommand DetailView { get; set; }

In my constructor i added

DetailView = new Command(PathToDetailView);

I created this method
void PathToDetailView()
{

        Which I do not know what should go here to redirect to DetailsPage for each item.

    }

I am kind of stuck in the DetailViewPage how to get the value.

I appreciate your help.
