Is there a way to supply a boolean statement in the isActive parameter within NavigationLink in SwiftUI?

Question

I'm trying to get a NavigationLink to trigger when a string is no longer nil. Is there anyway to do this or something similar?

NavigationLink(destination: MainView(), isActive: $settings.isLoggedS !=nil)

Any help is greatly appreciated!

You can program the link.

          @State var activeString : String = ""
          var body: some View {
            NavigationView{
                NavigationLink(destination: Text(""), isActive: Binding<Bool>(get: {self.activeString != ""}, set: { _ in
                }) ){
                    TextField("input", text: $activeString)}}}
