You can set a global key for your navigation:

final GlobalKey<NavigatorState> navigatorKey = GlobalKey<NavigatorState>();

Pass it to MaterialApp:

new MaterialApp(
      title: 'MyApp',
      onGenerateRoute: generateRoute,
      navigatorKey: navigatorKey,
    );

Push routes:

navigatorKey.currentState.pushNamed('/someRoute');
