You would need to pull the value into the app before deleting it. Or save it to a variable. Or Do you mean how do you refresh the items in the list? ---

No I mean to delete a particular row when it is deleted. ---

What do you mean by “pulling” the value?? ---

I think your advice might work…can u just show it so it’ll be much more clear?? ---

If your rows aren’t being updated you likely didn’t create the logic to do so. Unless you are using listeners to tell the app to update your listviewer it won’t happen automatically ---

It isn’t a list viewer…it is a data viewer list which works a bit differently from list viewers… anyway how do I use listeners to tell the app to update the rows (data viewer list) ?? ---

Either way (list or dataviewer) you’ll need to inform the app to update. You can do this with a listener block. Set the listener. Then When the listener notices a change, use code to update your data source for your data viewer. ---

Data viewer list does not have a way to directly connect to a Firebase database. Am I missing something here? ---

Where there is a will, there is a way I would set up a real-time listener on the node containing the changing data. When a change is observed the listener would fire a function to clear and repopulate the local data viewer. ---
