android - Flutter - Navigate to a new screen, and clear all the previous screens

Question

I used Navigator.push up to 6 screens to get to the payment page. After Payment, I want to push to the "Payment Successful" page then remove all the previous screens i.e using the back button will return to the very first screen.

NOTE: I have tried pushReplacementNamed and it doesn't work.

Answer 1

I figured it out. It was the Navigator.pushAndRemoveUntil function. Where i had to pass the PaymentSuccessful widget as the newRoute, and the "/Home" route as the predicate

  _navPaymentSuccessful(){
    Navigator.pushAndRemoveUntil(
      context, 
      MaterialPageRoute(
        builder: (context) => PaymentSuccessful()
      ), 
     ModalRoute.withName("/Home")
    );
  }
