To build a mobile app with a simple UI for both the frontend and backend, where users can interact similarly to the web interface of the VAPI assistant, you would typically start with the Client SDK for Flutter. The Flutter VAPI SDK will allow you to create the user interface and handle interactions on the client side.
However, for the backend functionality, especially if you need to handle voice processing, server-side logic, or integration with other systems, you would also need to use a Server SDK. The Server SDK would handle requests from your Flutter app, process them accordingly, and then send responses back to the client.
In summary, for a fully functional app with both frontend and backend capabilities, you would use the Flutter Client SDK for the mobile interface and a Server SDK for the backend services. If you need further assistance or have specific questions about implementation, please feel free to ask!
