aquí abajo un poco de código:

 import React, { Component } from 'react'; import { StyleSheet, Text, View } from 'react-native'; import { GiftedChat } from 'react-native-gifted-chat'; import { Dialogflow_V2 } from 'react-native-dialogflow'; import { dialogflowConfig } from './env'; const BOT_USER = { _id: 2, name: 'FAQ Bot', avatar: 'https://i.imgur.com/7k12EPD.png' }; class App extends Component { state = { messages: [ { _id: 1, text: `Hi! I am the FAQ bot 🤖 from Jscrambler.\n\nHow may I help you with today? `, createdAt: new Date(), user: BOT_USER } ] }; componentDidMount() { Dialogflow_V2.setConfiguration( dialogflowConfig.client_email, dialogflowConfig.private_key, Dialogflow_V2.LANG_ENGLISH_US, dialogflowConfig.project_id ); } handleGoogleResponse(result) { let text = result.queryResult.fulfillmentMessages[0].text.text[0]; this.sendBotResponse(text); } onSend(messages = []) { this.setState(previousState => ({ messages: GiftedChat.append(previousState.messages, messages) })); let message = messages[0].text; Dialogflow_V2.requestQuery( message, result => this.handleGoogleResponse(result), error => console.log(error) ); } sendBotResponse(text) { let msg = { _id: this.state.messages.length + 1, text, createdAt: new Date(), user: BOT_USER }; this.setState(previousState => ({ messages: GiftedChat.append(previousState.messages, [msg]) })); } render() { return ( <View style={{ flex: 1, backgroundColor: '#fff' }}> <GiftedChat messages={this.state.messages} onSend={messages => this.onSend(messages)} user={{ _id: 1 }} /> </View> ); } } export default App;
