Error While Navigating From Double Column Navigation View

[HaarisIqubal]

Hi I am making a app and I want to implement Double Column Navigation View in Mac, when I open my inside the main screen I easily navigate using Navigation Stack and Push and Pop my views but when I tried to open link from SideBar then I tried to open any link it shows error "No ObservableObject of type NavigationStack found. A View.environmentObject(_:) for NavigationStack may be missing as an ancestor of this view."

Can you please suggest me solution you help will highly appreciated.

Sidebar View
NavigationStackView{ NavigationLink(destination: HomeViewMac().environment(\.managedObjectContext, persistenceController.container.viewContext).environmentObject(NavigationStack()), label:{ Image(systemName: "square.grid.2x2.fill") Text("Dashboard") }) }
Main View
`
List{
ForEach(self.fetchedDecks){ item in
if item.deckIsFavourite {
PushView(destination: DeckDetailView(deck: item, deckID: $item.deckId),label:{
Text(deck.deckTitle!)
})
}
}
PushView(destination: FavouriteView(), label: {
Text("See more")
})

    }

Hi @HaarisIqubal. It would be great to have a minimum viable example to try and debug. If I got what you mean, I think the problem is that you are trying to use the navigation stack environment object from a completely different view hierarchy. What about having two different NavigationStackView? Something like:

struct ContentView: View {
    @StateObject var mainNavStack = NavigationStack()
    @StateObject var secondaryNavStack = NavigationStack()

    var body: some View {
        NavigationView {
            NavigationStackView(navigationStack: mainNavStack) {
                MainView()
            }
            NavigationStackView(navigationStack: secondaryNavStack) {
                SecondaryView()
            }
        }
        .navigationViewStyle(DoubleColumnNavigationViewStyle())
    }
}

struct MainView: View {
    var body: some View {
        PushView(destination: MainChild()) {
            Text("PUSH TO MAIN CHILD")
        }
    }
}

struct MainChild: View {
    var body: some View {
        PopView() {
            Text("POP TO MAIN VIEW")
        }
    }
}

struct SecondaryView: View {
    var body: some View {
        PushView(destination: MainChild()) {
            Text("PUSH TO SECONDARY CHILD")
        }
    }
}

struct SecondaryChild: View {
    var body: some View {
        PopView() {
            Text("POP TO SECONDARY VIEW")
        }
    }
}

You can even store your navigation stack (or stacks) somewhere, inject them in your NavigationStackView hierarchy (or hierarchies) and access them from wherever you want to programmatically trigger push and pop operations.
