how to hide navigation bar on particular screen in SwiftUI?-CodePudding

I am navigating from one screen to another on previous screen i am hiding navigation bar but on second screen I want to show navigation bar but in mu case its hiding on second screen also.

navigation bar hidden on first screen as

.navigationBarHidden(true)

How can i show navigation bar on second screen? (I am NOT using navigation view on either screen)

My First parent screen has

            NavigationView {
//design
}
.navigationBarTitle("ABCScreen", displayMode: .inline)
                .navigationViewStyle(StackNavigationViewStyle())

Thank you for help.

The possible approach to hide navigation bar in root view and show in child subviews.

struct FirstNavigationView: View {
    @State private var hideBar = true // <<  hide state
    var body: some View {
        NavigationView {
            VStack {
                Text("FirstView")
                Divider()
                NavigationLink("Goto Child", destination: NextChildView(index: 1))
                 .simultaneousGesture(TapGesture().onEnded {
                    self.hideBar = false     // << show
                 })
            }
            .navigationBarHidden(hideBar)
        //    .navigationBarTitle("Back to Root") // << choice 
            .onAppear {
                self.hideBar = true  // << hide on back
            }
        }
    }
}

The only needed modifications is in root view.

For your first screen you can add .navigationBarHidden(true) inside your NavigationView to hide it and false on second screen to unhide.

FIRST SCREEN:

NavigationView{
        Button(action: {}, label: {
            Text("Button")
        })
        .navigationBarHidden(true) //This flag will hide your navigationBar
    }

SECOND SCREEN:

NavigationView{
        Button(action: {}, label: {
            Text("Button")
        })
        .navigationBarHidden(false) //This flag will unhide your navigationBar
    }
