'Can we add custome text inside a listview.builder in flutter
I made a chat application using flutter. I am loading messages using ListView.builder. In this chat-app, sender can end conversation(think like doctor patient doctor can end the coversation). So I am trying to show a message, like "conversation ended" in both side.
But if some reason doctor start a conversation again, that messages needs to show below that "conversation ended" message. Like in the whatsapp date or facebook messanger date.
I am struggling to do that because of the listview builder. Is there way to do with listview builder or are there any other options?
Here is my message widget.

controller: _refreshController,

enablePullDown: false,

return InkWell(
onLongPress: () {
