Answer 3

@aziza is the right answer but in some miscellaneous situation in my case

  class RouteGenerator {
  static Route<dynamic> generateRoute(RouteSettings settings) {
    switch (settings.name) {
      case '/':
        MaterialPageRoute(builder: (_) => MyScaffold());
        break;
      case '/homechart':
         MaterialPageRoute(builder: (_) => analytics());
        break;
    }
  }
}

I forget to return keyword and IDE not showing any error. showing this kind of error.

Solution is like this :

class RouteGenerator {
  static Route<dynamic> generateRoute(RouteSettings settings) {
    switch (settings.name) {
      case '/':
     return   MaterialPageRoute(builder: (_) => MyScaffold());
        break;
      case '/homechart':
       return   MaterialPageRoute(builder: (_) => analytics());
        break;
    }
  }
}

Answer 4

In my case the error was because i deleted the route from main.dart and forgot the update the change in other files

Answer 5

You have instantiated two MaterialApp widget. You need to remove the one in MyApp class.

For push

Navigator.of(context).pushNamed('/screen1')

For Pop: "popAndPushNamed"

Navigator.of(context).popAndPushNamed('/screen4');

Answer 6

try this :

onPressed: () {
    Navigator.push(
      context,
      new MaterialPageRoute(
        builder: (context) => new ListaDeCompras(),
      ),
    );
  },
