How to perform an action after NavigationLink is tapped?

Question

I have a Plus button in my first view. Looks like a FAB button. I want to hide it after I tap some step wrapped in NavigationLink. So far I have something like this:

I'm using the following code. I prefer it to just NavigationLink by itself because it lets me reuse my existing ButtonStyles.

struct NavigationButton: View {
    var action: () -> Void = { }
    var destination: () -> Destination
    var label: () -> Label

    @State private var isActive: Bool = false

    var body: some View {
        Button(action: {
            self.action()
            self.isActive.toggle()
        }) {
            self.label()
              .background(
                ScrollView { // Fixes a bug where the navigation bar may become hidden on the pushed view
                    NavigationLink(destination: LazyDestination { self.destination() },
                                                 isActive: self.$isActive) { EmptyView() }
                }
              )
        }
    }
}

// This view lets us avoid instantiating our Destination before it has been pushed.
struct LazyDestination: View {
    var destination: () -> Destination
    var body: some View {
        self.destination()
    }
}

And to use it:

var body: some View {
  NavigationButton(
    action: { print("tapped!") },
    destination: { Text("Pushed View") },
    label: { Text("Tap me") }
  )
}
