Flutter-导航到新屏幕，然后清除以前的所有屏幕

我想到了。这是

Navigator.pushAndRemoveUntil

PaymentSuccessful

newRoute

"/Home"

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