Flutter remove all routes

I want to develop a logout button that will send me to the log in route and remove all other routes from the Navigator. The documentation doesn't seem to explain how to make a RoutePredicate or have any sort of removeAll function.

Solution

  • 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.
