Hi Wayne,
We apologize for the delay in responding to your query
regarding 'Stream text into the response'. After investigating your
request, we believe that what you are looking for is the 'load more' feature
for fetching messages in a chat conversation.
You can use the SfChat.LoadMoreBehavior to implement this
functionality in your application. This will allow users to scroll to the top
of the message list and fetch messages on demand, either automatically or by
tapping the 'load more' button.
For more information on how to implement this feature,
please refer to our User Guide, which provides detailed instructions and code
examples.
