WidgetTemplate as child of a Stack

[eminfedar]

I'm trying to have this widget overlay in view! macro.

Example.blp (GTK Blueprint):

Adw.ToastOverlay toast_overlay {
  child:
  Gtk.Stack stk_pages {
    margin-all: 11;
    margin-top: 7;

    Gtk.StackPage {
      name: "main";
      child: 
      Box {
        orientation: vertical;
      }
    }
    Gtk.StackPage {
      name: "settings";
      child: 
      Box {
        orientation: vertical;
      }
    }
  }
}

But I couldn't figure it out how to do it with WidgetTemplate.

I separated content of StackPages in blueprint example to different WidgetTemplates:

#[relm4::widget_template(pub)]
impl WidgetTemplate for SettingsPage {
    view! {
        gtk::Box {
            set_orientation: gtk::Orientation::Vertical,
            set_spacing: 3,
        }
    }
}
#[relm4::widget_template(pub)]
impl WidgetTemplate for MainPage {
    view! {
        gtk::Box {
            set_orientation: gtk::Orientation::Vertical,
            set_spacing: 3,
        }
    }
}

My first try( it doesn't work :)) view! macro:

    view! {
        gtk::Box {
            set_orientation: gtk::Orientation::Vertical,

            adw::ToastOverlay {

                #[wrap(Some)]
                set_child = &gtk::Stack{
                    set_margin_all: 11,
                    set_margin_top: 7,

                    #[template]
                    add_child = &MainPage {} -> {
                        // Set the title of the stack page
                        set_name: "main",
                    },

                    #[template]
                    add_child = &SettingsPage {} -> {
                        // Set the title of the stack page
                        set_name: "settings",
                    },
                }
            }

        }
    }

How can I create this widget overlay and how can I use template widget as stack page?

Actually it is working (my error was something else):

adw::ToastOverlay {
        #[wrap(Some)]
        set_child = &gtk::Stack{
        set_margin_all: 11,
        set_margin_top: 7,

        #[template]
        add_child = &SettingsPage {} -> {
            set_name: "settings",
        },

        #[template]
        add_child = &MainPage {} -> {
            set_name: "main",
        },
    }
}
