restorablePushReplacementNamed<T extends Object?, TO extends Object?> static method
- BuildContext context,
- String routeName, {
- TO? result,
- Object? arguments,
Replace the current route of the navigator that most tightly encloses the
given context by pushing the route named routeName
and then disposing
the previous route once the new route has finished animating in.
Unlike Routes pushed via pushReplacementNamed, Routes pushed with this method are restored during state restoration according to the rules outlined in the "State Restoration" section of Navigator.
If non-null, result
will be used as the result of the route that is
removed; the future that had been returned from pushing that old route
will complete with result
. Routes such as dialogs or popup menus
typically use this mechanism to return the value selected by the user to
the widget that created their route. The type of result
, if provided,
must match the type argument of the class of the old route (TO
).
The route name will be passed to the Navigator.onGenerateRoute callback. The returned route will be pushed into the navigator.
The new route and the route below the removed route are notified (see Route.didPush and Route.didChangeNext). If the Navigator has any Navigator.observers, they will be notified as well (see NavigatorObserver.didReplace). The removed route is notified once the new route has finished animating (see Route.didComplete). The removed route's exit animation is not run (see popAndPushNamed for a variant that animates the removed route).
Ongoing gestures within the current route are canceled when a new route is pushed.
The T
type argument is the type of the return value of the new route,
and TO
is the type of the return value of the old route.
To use pushReplacementNamed, a Navigator.onGenerateRoute callback must be provided.
The provided arguments
are passed to the pushed route via
RouteSettings.arguments. Any object that is serializable via the
StandardMessageCodec can be passed as arguments
. Often, a Map is used
to pass key-value pairs.
The arguments may be used in Navigator.onGenerateRoute or Navigator.onUnknownRoute to construct the route.
The method returns an opaque ID for the pushed route that can be used by the RestorableRouteFuture to gain access to the actual Route object added to the navigator and its return value. You can ignore the return value of this method, if you do not care about the route object or the route's return value.
