Invoke Payment For Testing Purpose Only

startInstamojo() async {
    dynamic result = await Navigator.push(
        context,
        MaterialPageRoute(
            builder: (ctx) => InstamojoScreen(
                  isLive: false,
                  body: CreateOrderBody(
                      buyerName: "EvilRAT Technologies",
                      buyerEmail: "ceo@evilrattechnologies.com",
                      buyerPhone: "+91 7004491831",
                      amount: "300",
                      description: "Test Payment"),
                  orderCreationUrl:
                      "https://sample-sdk-server.instamojo.com/order", // The sample server of instamojo to create order id.
                )));

    setState(() {
      _paymentResponse = result.toString();
    });
}

startInstamojo() async {
    dynamic result = await Navigator.push(
        context,
        MaterialPageRoute(
            builder: (ctx) => InstamojoScreen(
                  isLive: true,
                  name: widget.package["name"].toString(),
                  orderId: orderId,
