title: Flutter and DialogFlow Chatbot
body: <p>I am trying to make a chatbot for my Flutter app using DialogFlow. At first I used the API V2, and I get this error : <a href="https://i.stack.imgur.com/fCZ6S.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/fCZ6S.png" alt="First error"></a></p>
  
  <p>I searched online, and the only answer I found is to switch to "flutter_dialogflow.dart" package instead of the "dialogflow_v2.dart" package everything seemed to work just fine at the first glance, but when I wrote "Hi how are you doing?" the flowing error appears: </p>
  
  <p><a href="https://i.stack.imgur.com/WSTEO.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/WSTEO.png" alt="Second error"></a>
  P.S: Everything is activated on DialogFlow
  Please help! Thank you</p>
