Hello! Im trying function calling feature with this example:

  void gptFunctionCalling() async {
    final request = ChatCompleteText(
        messages: [
          Messages(
              role: Role.user,
              content: "What is the weather like in Boston?",
              name: "get_current_weather"),
        ],
        maxToken: 200,
        model: GptTurbo0631Model(),
        functions: [
          FunctionData(
              name: "get_current_weather",
              description: "Get the current weather in a given location",
              parameters: {
                "type": "object",
                "properties": {
                  "location": {
                    "type": "string",
                    "description": "The city and state, e.g. San Francisco, CA"
                  },
                  "unit": {
                    "type": "string",
                    "enum": ["celsius", "fahrenheit"]
                  }
                },
                "required": ["location"]
              })
        ],
        functionCall: FunctionCall.auto);
