initialRoute property

String? initialRoute
final

The name of the first route to show, if a Navigator is built.

Defaults to dart:ui.PlatformDispatcher.defaultRouteName, which may be overridden by the code that launched the application.

If the route name starts with a slash, then it is treated as a "deep link", and before this route is pushed, the routes leading to this one are pushed also. For example, if the route was /a/b/c, then the app would start with the four routes /, /a, /a/b, and /a/b/c loaded, in that order. Even if the route was just /a, the app would start with / and /a loaded. You can use the onGenerateInitialRoutes property to override this behavior.

Intermediate routes aren't required to exist. In the example above, /a and /a/b could be skipped if they have no matching route. But /a/b/c is required to have a route, else initialRoute is ignored and Navigator.defaultRouteName is used instead (/). This can happen if the app is started with an intent that specifies a non-existent route.

The Navigator is only built if routes are provided (either via home, routes, onGenerateRoute, or onUnknownRoute); if they are not, initialRoute must be null and builder must not be null.

Changing the initialRoute will have no effect, as it only controls the initial route. To change the route while the application is running, use the Navigator or Router APIs.
