if you are running your app on a physical device or emulator, you must exchange your [MaterialApp] for a [GetMaterialApp] but GetMaterialApp if exist

Describe the bug You are trying to use contextless navigation without a GetMaterialApp or Get.key. If you are testing your app, you can use: [Get.testMode = true], or if you are running your app on a physical device or emulator, you must exchange your [MaterialApp] for a [GetMaterialApp].

**Reproduction code Get.toNamed("/configuracion");

example:

Future<void> main() async {
  // WidgetsFlutterBinding.ensureInitialized();
  await GetStorage.init();
  SystemChrome.setPreferredOrientations([DeviceOrientation.portraitUp]);
  runApp(TendaGo());
}

class TendaGo extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    Get.put(GlobalController());
    return GetMaterialApp(
      initialRoute: '/splash',
      translations: Messages(),
      locale: Get.deviceLocale,
      fallbackLocale: Locale('en'),
      localizationsDelegates: [
        GlobalMaterialLocalizations.delegate,
        GlobalWidgetsLocalizations.delegate,
        GlobalCupertinoLocalizations.delegate,
      ],
      supportedLocales: [
        const Locale('es', 'ES'), // Arabic, no country code
      ],
      theme: ThemeData(
          primaryIconTheme: IconThemeData(
        color: Colors.white,
      )),
      debugShowCheckedModeBanner: false,
      title: 'Tenda Go',
      home: SplashPage(),
      initialBinding: SplashBinding(),
      getPages: AppPages.pages,
    );
  }
}

Maybe you are calling the navigator before the GetMaterialApp is attached. Would you be calling Get.toNamed("/configuracion"); in onInit or class constructor?

Get.toNamed("/configuracion"); is called in onPress in a button but don't work

I think the problem is probably that you are trying to navigate with contextless. If you are trying to move from the splashscreen controller to the HomePage (for example), you can wrap Get.to() inside a Future, and this will automatically make it time for GetMaterialApp to be loaded. This worked for me.
