Project Setup and Authentication
- First of all, we need to create a Google Cloud Platform Project using Console Google Cloud
- Create or select an existing GCP project.
- From the GCP console, go to APIs and Services and click on credentials.
- Click on Create credentials and choose Service account key.
- Select your service account from the dropdown, choose JSON and click Create. This will download the JSON key to your computer. Save it securely.
- We downloaded a JSON file with all our data.
In your project create folder assets(folder name recommended optional)
Move file json in your project in folder created

open file pubspec.yaml

flutter:
uses-material-design: true
assets:
- assets/your_file_downloaded_google_cloud.json

Import dialogflow_v2

import 'package:flutter_dialogflow/dialogflow_v2.dart';

Code

AuthGoogle authGoogle = await AuthGoogle(fileJson: "Asset Your File Json").build();
// Select Language.ENGLISH or Language.SPANISH or others...
Dialogflow dialogflow =Dialogflow(authGoogle: authGoogle,language: Language.ENGLISH); 
AIResponse response = await dialogflow.detectIntent("Your Query");

Example

AuthGoogle authGoogle = await AuthGoogle(fileJson: "assets/your_file_downloaded_google_cloud.json").build();
Dialogflow dialogflow = Dialogflow(authGoogle: authGoogle,language: Language.ENGLISH);
AIResponse response = await dialogflow.detectIntent("Hi!!!");
print(response.getMessage())

Or Get List Message type Card


Call function response.getListMessage() 
response List<dynamic>
example 
new CardDialogflow(response.getListMessage()[0]).title
Convert first item in CardDialogflow for worked easy
CardDialogflow have

title
subtitle
imageUri
List buttonss
- each button have text and postback

Or Setup custom authentication (session)


Get a session id from your backend server after authentication.(Eg: OAuth Token)
Pass the session id a named parameter 'sessionId' to AuthGoogle function.
On the dialogflow fulfillment, access it inside `agent.session` (WebhookClient.session)
and apply your session logic

Example: AuthGoogle authGoogle = await AuthGoogle(fileJson: "assets/your_file_downloaded_google_cloud.json", sessionId: "YOUR_CUSTOM_SESSION_ID").build(); Dialogflow dialogflow = Dialogflow(authGoogle: authGoogle,language: Language.ENGLISH); AIResponse response = await dialogflow.detectIntent("Hi!!!"); print(response.getMessage())
