You have to override native library code.

Hi ​@chard1988 :

You're right — the Freshchat.showConversations() method in the Flutter SDK loads the default conversation UI, and currently, the SDK doesn’t provide a built-in way to customize this interface or directly access messages for building a custom UI.

If you’d like to implement your own UI for listing topics (channels) and showing messages when a topic is tapped, you can achieve this using the Freshchat REST APIs. Here's how:

1. List Topics (Channels):
   Use GET /channels to retrieve all available topics for the user.

2. Get Conversations for a Channel:
   When a topic is tapped, call GET /conversations?channel_id=... to fetch conversations tied to that channel and user.

3. Fetch Messages in a Conversation:
   Use GET /conversations/{conversation_id}/messages to get the full chat history between the user and agent.

4. Send Messages:
   You can send messages using POST /conversations/{conversation_id}/messages.

This approach allows you full control to build a custom chat experience in Flutter. However, since these APIs are generally meant for server-side use, you may need to handle authentication via a backend service to securely fetch and post messages on behalf of the user.
