Change button text on last image of Slider in SwiftUI - ios

Question

I have an image slider with dot indicator named "Onboardingslider". I have used it in my another screen "onboard4" , I want to change the text of "next" button to "get started" only on last image of slider otherwise it stays "next".
I have tried a lot of things but nothing works
Please help me I'm a newbie
struct onboard4: View {
#State var showModal = false
#State var maxlogoheight: CGFloat = 0
#State var isLinkActive = false
var body: some View {
NavigationView {
ZStack{
//max height will be width of the screen
GeometryReader{ proxy -> AnyView in
let height = proxy.frame(in: .global).height
DispatchQueue.main.async {
if maxlogoheight == 0 {
maxlogoheight = height
}
}
return AnyView (
ZStack{
Image("Logo")
.resizable()
.scaledToFit()
.offset(x: getReact().width/3.5, y: -height/1.25)
}//zstack 2
// .padding(.leading,10)
)//anyview
}//end of gr
.frame(maxHeight: getReact().width)
VStack{
Onboardingslider()
Button(action: {
showModal = true
}) {
ZStack{
Text("Next")
.foregroundColor(Color.white)
.fontWeight(.bold)
.frame (width: 295, height: 30)
.padding()
.background(Color("YellowAccent"))
.cornerRadius(20)
.shadow(color: .gray, radius: 5, x: 0, y: 4)
Image("NextButtonOnboard")
}
}
.fullScreenCover(isPresented: $showModal) {
LoginView() }
.offset(y: getSafearea().bottom + -55)
}//vstack
Button(action: {}, label: {
Text("Continue to the listing service")
.underline()
})
.foregroundColor(Color.black)
.offset(y: getSafearea().bottom + 310)
}//zstack
.background(
NavigationLink(destination: LoginView(), isActive: $isLinkActive) {
EmptyView()
}
.hidden()
