         "EMAIL": "you@email.com",
         "AMOUNT": 100,
         "CURRENCY": "NGN",
         "PAYMENT_FOR": "Testing API",
         "PAYSTACK_PUBLIC_KEY":paystack_pub_key,
         "BACKEND_URL": paystack_backend_url,
       });
     } on PlatformException catch (e) {
       result = e.message;
       print(e.message);
     }
