Failure delivering result ResultInfo

[kuxtal]

I have a problem to implement mad_pay with flutter on Android Application.
I already followed the guide and example, but I can't receive response after payment.
I'm using a Test enviroment and android test cards, and I have configured a MainActivity with onActivityResult.

I have configured the google pay button in this form:

googlePayButton: GooglePayButton(
                  width: 290,
                  height: 120,
                  style: GooglePayButtonStyle.black,
                  type: GooglePayButtonType.pay,
                  request: PaymentRequest.google(
                    paymentNetworks: <PaymentNetwork>[
                      PaymentNetwork.amex,
                      PaymentNetwork.discover,
                      PaymentNetwork.interac,
                      PaymentNetwork.jcb,
                      PaymentNetwork.mastercard,
                      PaymentNetwork.visa,
                      PaymentNetwork.mir,
                    ],
                    google: googleParameters,
                    currencyCode: 'USD',
                    countryCode: 'US',
                    paymentItems: items,
                  ),
                  onPaymentResult: (PaymentResponse? req) {
                    setState(() {
                      result = 'GooglePayButton, Try to pay:\n${req?.token}';
                    });
                  },
                  onError: (Object? e) {
                    setState(() {
                      result = 'GooglePayButton, Error:\n$e';
                    });
                  },

I have configured MainActivity:

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        Log.i(TAG, "Card info: $resultCode - $requestCode - $data");

         if(resultCode != RESULT_CANCELED && data != null){
             super.onActivityResult(requestCode, resultCode, data);
         }
}

I'm using mad_pay 2.2.12, I when I finalized the pay, the app doesn't enter onPaymentResult neither onError, however onActivityResult I can see:

Card info: -1 - 991 - Intent { (has extras) }

And after I receive
