To remove all the routes below the pushed route, use a RoutePredicate that always returns false (e.g. (Route<dynamic> route) => false ). The removed routes are removed without being completed, so this method does not take a return value argument. The newly pushed route and its preceding route are notified for Route.
A route that blocks interaction with previous routes. ModalRoutes cover the entire Navigator. They are not necessarily opaque, however; for example, a pop-up menu uses a ModalRoute but only shows the menu in a small box overlapping the previous route. The T type argument is the return value of the route.
I was able to accomplish this with the following code:
Navigator.of(context)
.pushNamedAndRemoveUntil('/login', (Route<dynamic> route) => false);
The secret here is using a RoutePredicate that always returns false (Route<dynamic> route) => false
. In this situation it removes all of the routes except for the new /login
route I pushed.
i can done with the following code snippet :
Navigator.of(context).pushAndRemoveUntil(MaterialPageRoute(builder: (context) =>
LoginScreen()), (Route<dynamic> route) => false),
if you want to remove all the route below the pushed route, RoutePredicate always return false, e.g (Route route) => false.
Another alternative is popUntil()
Navigator.of(context).popUntil(ModalRoute.withName('/root'));
This will pop all routes off until you are back at the named route.
Another solution is to use pushAndRemoveUntil()
. To remove all other routes use ModalRoute.withName('/')
Navigator.pushAndRemoveUntil(
context,
MaterialPageRoute(builder: (BuildContext context) => Login()),
ModalRoute.withName('/')
);
Reference: https://api.flutter.dev/flutter/widgets/NavigatorState/pushAndRemoveUntil.html
In case you want to go back to the particular screen and you don't use named router can use the next approach
Example:
Navigator.pushAndRemoveUntil(context,
MaterialPageRoute(builder: (BuildContext context) => SingleShowPage()),
(Route<dynamic> route) => route is HomePage
);
With route is HomePage you check the name of your widget.
