How can I retrieve data by url based on index Flutter GETX

So here I have a problem, when I want to pass data using a url based on an index using the getx method,

Here I want when I click on the next page to take the url, for example, click "Dana" then go to the url "/danakonven", then it will appear according to the url direction

postman :: http://192.168.100.207:8080/konven

postman :: http://192.168.100.207:8080/danakonven

Here's the source code that I have on the first page,on the first page the on tap section, how about the contents so that the data can be sent

 final ProductController productController = Get.put(ProductController());

  @override
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(
          title: Text(AppString.productList),
        ),
        body: Container(
            child: Column(children: [
          Obx(() {
            if (productController.isLoading.value)
              return Center(child: CircularProgressIndicator());
            else
              return Expanded(
                  child: ListView.builder(
                      itemCount: productController.productList.length,
                      itemBuilder: (context, index) {
                        return Column(
                          children: [
                            GestureDetector(
                                onTap: () {
                                // How can I retrieve data by url based on index 
                                },
                                child: Card(
                                    // color: Colors.blue[900],
                                    elevation: 5,
                                    margin: const EdgeInsets.all(10),
                                    child: ListTile(
                                        title: Text(
                                            productController
                                                .productList[index].kontenMenu,
                                            style: (TextStyle(
                                              fontSize: 20,
                                            ))))))
                          ],
                        );
                      }));
          })
        ])));

here I am confused to make a second page can you give an example for the second page command so that it can display from the first page
