NavTitle and NavToolbar

func (n *viewNode) NavTitle(title string) *viewNode
func (n *viewNode) NavToolbar(items ...ToolbarItem) *viewNode
 
type ToolbarItem struct { /* opaque */ }
 
func ToolbarLeading(v any) ToolbarItem
func ToolbarTrailing(v any) ToolbarItem

The NavStack reads these values from the visible view's modifier set and draws them in the title bar.

Title

func (HomeView) Body(s *gova.Scope) gova.View {
    return gova.VStack(
        gova.Text("Home"),
    ).NavTitle("Home")
}

func (v DetailView) Body(s *gova.Scope) gova.View {
    nav := gova.UseNav(s)
 
    return gova.VStack(content).
        NavTitle(fmt.Sprintf("Item %d", v.ID)).
        NavToolbar(
            gova.ToolbarTrailing(gova.Button("Edit", func() {
                nav.Push(EditView{ID: v.ID})
            })),
        )
}

ToolbarLeading and ToolbarTrailing wrap any view so they can be placed on the leading or trailing side of the title bar. If the stack has more than one view, the bar also shows a back button on the leading side; you do not need to add it yourself.
