Answer 1

You Need to Add GetMaterialApp In Your Main.dart file for GetX .

Thanks . Here is the Demo :

import 'package:flutter/material.dart';
import 'package:get/get.dart';
import 'package:getxpro/view/cartPage.dart';
import 'package:getxpro/view/home.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return GetMaterialApp( //for navigation dont forget to use GetMaterialApp
      title: 'getXpro',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      initialRoute: '/',
      routes: {
        '/': (context) => HomePage(),
        '/cart': (context) => CartPage(),
      },
    );
  }
}

Since the question lacks information such as using the Get package to handle the navigation, it looks like there is a missing Get.Key so you have to add

get.testmode=true

inside your GetMaterialApp()
