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

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")
    );
  }
