        child: GestureDetector(
          onTap: getData,
          child: Container(
            width: 100,
            height: 100,
            color: Colors.red,
          ),
        ),
      ),
    );
  }
}

I have allowed the Internet permission, wifi is on on lapy and phone

I am providing the shop name like: verden-app.myshopify.com, and the storeFrontApiToken(from the private app which I have created), I have allowed read_write permission for all the options as well, help, please?

I am just running the given example and want to print data from my store
