I have a DialogFlow agent that I call using intents from my Flutter code. In my desired intent, I have fulfillment enabled to call my Node.js backend.

In my intent, I have a country_code parameter of the system entity type @sys.geo-country-code.

I trigger this intent in Flutter using an event and pass the required parameters. Here is the line of code in Flutter:

var parameters = "'parameters' : {'country_code': '$countryCode'}";

and here is a sample request for the parameters:

"parameters": { 

   "country_code": "US"

}

I expect that when this request reaches DialogFlow, it transforms the country_code input to an object that looks something like this:

{ 

   "alpha-2":"US",

   "alpha-3":"USA",

   "name":"United States of America",

   "numeric":840

}

However, when the fullfillment request reaches my Node.js backend, I see that DialogFlow is not transforming the input country_code to this object. Rather, the fulfillment request is done with the same input as I provided to DialogFlow. When I do the same thing with the DialogFlow console, it works perfectly. So, it seems that something is not correct in the way I call the DialogFlow API from Flutter. However, I can't say what.

Can someone please help?
