}

Dialogflow v2

• Dialogflow](https://dialogflow.com/) register and create new Agent
• 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())
