flutter: Could not find a generator for route RouteSettings("/", null) in the _WidgetsAppState.                    
flutter: Generators for routes are searched for in the following order:         
flutter:  1. For the "/" route, the "home" property, if non-null, is used.      
flutter:  2. Otherwise, the "routes" table is used, if it has an entry for the route.                              
flutter:  3. Otherwise, onGenerateRoute is called. It should return a non-null value for any valid route not       
flutter: handled by "home" and "routes".

@sunnyshingala The exception says Could not find a generator for route RouteSettings("/", null) in the _WidgetsAppState. Did you miss to add / to your MaterialApp routes? Is the issue still relevant?

So i finally found a working solution.

Start the app with the "/" named route. In this case, the app starts on the FirstScreen widget.
When navigating to the "/" route, build the FirstScreen widget.
When navigating to the "/second" route, build the SecondScreen widget.
MaterialApp(
initialRoute: '/',
routes: {
'/': (context) => FirstScreen(),
'/second': (context) => SecondScreen(),
},
);
