I have been trying a simple navigation from toolbar, however the navigation button just does not work, can any one suggest where the issue might be

struct MyAdsPageView: View {
    var documents = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0]
    @State  var gotoAdd = false
    @ObservedObject var dataAd: DataController
    @Environment(\.managedObjectContext) var managedObjectContext
    @State var gotoEdit = false

    var body: some View {

        NavigationView {
            List {

                ForEach(dataAd.carSheet, id:\.self) { path in
                    NavigationLink(destination: DetailView(cardata: path)) {
                        if let data = try? Data(contentsOf: documents.appendingPathComponent(path.imageNameTemp)), let loaded = UIImage(data: data) {

                            HStack {

                                Text(path.makeYearTemp)
                                    .padding()
                            }
                            .swipeActions {
                                Button {
                                    gotoEdit = true

                                } label: {
                                    Label("Edit", systemImage: "pencil")
                                }
                                .tint(.red)

                            }

                            NavigationLink("", isActive: $gotoEdit, destination: {
                                EditViewData(cardata: path, carid: path.caridTemp, carBrand: path.brandNameTemp)
                            })

                            NavigationLink("", isActive: $gotoAdd) {
                                AddView(dataController: DataController.shared)
                            }

                        }

                    }

                }

            }

            .navigationTitle("Car List")

            .toolbar {
                ToolbarItem {
                    Button("Add Car") {  <--------- this link is just not navigating, i tried NavigationStack as well
                        gotoAdd = true
                    }
                }
            }
        }

    }

}

Maybe missing the ,destination?

NavigationLink("", isActive: $gotoAdd, destination:  {
                                AddView(dataController: DataController.shared)
                            })

@Bnerd, thanks, i tried that but i can see the button is tapped and the control goes inside and toggles the value but no navigation, i am thinking some issue with multiple navigations links, but in so far i know , this is first time its not working with multiple nav links

This link is inside your ForEach

NavigationLink("", isActive: $gotoAdd) {
    AddView(dataController: DataController.shared)
}

So when you set gotoAdd to true using the Button, which of the views in the ForEach is it meant to use for the navigation destination? It just doesn't know which one to use, and you have not specified it, so it does nothing.
