Usage #

  • Dialogflow 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_v2/flutter_dialogflow_v2.dart';
  • Code examples
AuthGoogle authGoogle = await AuthGoogle(fileJson: 'assets/your_file.json').build();
Dialogflow dialogflow = Dialogflow(authGoogle: authGoogle, sessionId: '123456');
DetectIntentResponse response = await dialogflow.detectIntent(
  DetectIntentRequest(
    queryInput: QueryInput(
      text: TextInput(
        text: 'Hello from flutter!',
        languageCode: Language.english,
      ),
    ),
    queryParams: QueryParameters(
      resetContexts: true,
    ),
  ),
);
  • or if you simply want to simple query some text:
AuthGoogle authGoogle = await AuthGoogle(fileJson: 'assets/your_file.json').build();
Dialogflow dialogflow = Dialogflow(authGoogle: authGoogle, sessionId: '123456');
DetectIntentResponse response = await dialogflow.detectIntentFromText('Hello!');
  • get text response
response.queryResult.queryText;
  • or list of messages
response.queryResult.fulfillmentMessages;
