pushNamed<T extends Object?> static method

  1. @optionalTypeArgs
Future<T?> pushNamed<T extends Object?>(
  1. BuildContext context,
  2. String routeName,
  3. {Object? arguments}

Push a named route onto the navigator that most tightly encloses the given context.

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 previous route (if any) are notified (see Route.didPush and Route.didChangeNext). If the Navigator has any Navigator.observers, they will be notified as well (see NavigatorObserver.didPush).

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 route.

To use pushNamed, an Navigator.onGenerateRoute callback must be provided,

Returns a Future that completes to the result value passed to pop when the pushed route is popped off the navigator.

The provided arguments are passed to the pushed route via RouteSettings.arguments. Any object can be passed as arguments (e.g. a String, int, or an instance of a custom MyRouteArguments class). 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.

Typical usage is as follows:
void _didPushButton() {
  Navigator.pushNamed(context, '/settings');

The following example shows how to pass additional arguments to the route:
void _showBerlinWeather() {
    arguments: <String, String>{
      'city': 'Berlin',
      'country': 'Germany',

The following example shows how to pass a custom Object to the route:
class WeatherRouteArguments {
  WeatherRouteArguments({ required this.city, required this.country });
  final String city;
  final String country;

  bool get isGermanCapital {
    return country == 'Germany' && city == 'Berlin';

void _showWeather() {
    arguments: WeatherRouteArguments(city: 'Berlin', country: 'Germany'),
