Appending sent messages in ListViewer

One of the students made this thunkable project where they have to make a chat app between a patient and a doctor. The app works fine if the patient and doctor are chatting alternatively. The realtime database is getting updated when a patient/doctor is sending consecutive messages, but the list viewer is not appending the values.

How to show messages consecutively sent by one person in listviewer?

Hi @gayathri.jayakumare5 - can you share a screenshot of the block you are using to update the listviewer?

Also, why are you using a list viewer for a chat app? Something like this might look a little nicer?

it’s there in the project I have shared, actually, we are using list viewer to display the messages sent, implementing list viewer. list viewer gets data from firebase RTDB. it’s for kids.
