        //Host the Server Side Code on your Server and use your URL here. The following URL may or may not work. Because hosted on free server.
        //Server Side code url: https://github.com/mrdishant/Paytm-Plugin-Server
        var url = 'https://desolate-anchorage-29312.herokuapp.com/generateTxnToken';

        var body = json.encode({
          "mid": mid,
          "key_secret": PAYTM_MERCHANT_KEY,
          "website": website,
          "orderId": orderId,

            body: body,
            headers: {'Content-type': "application/json"},
          );
          print("Response is");
          print(response.body);
          String txnToken = response.body;
          setState(() {
            payment_response = txnToken;
          });

          var paytmResponse = Paytm.payWithPaytm(
              mid, orderId, txnToken, amount.toString(), callBackUrl, testing);

          paytmResponse.then((value) {
            print(value);
            setState(() {
              loading = false;
              print("Value is ");
              print(value);
              if(value['error']){
                payment_response = value['errorMessage'];
              }else{
                if(value['response']!=null){
                  payment_response = value['response']['STATUS'];
                }
              }
              payment_response += "\n"+value.toString();
