I am quite new to both using Flutter and Rasa and was wondering how well they would be able to communicate with one another. I did see some previous topics on integration which does seem to direct towards as REST API approach; if that’s the case then it seems pretty logical.
Yes, the easiest way to do custom integrations with Rasa is via a REST Channel. This allows you to post the user’s messages to an API endpoint and receive the bot’s responses. You can find a detailed explanation of how to set it up here in our docs.
