How to create a card in a listview with button press on Flutter?

Listview will be empty after the click I would like to create a card in the ListView on flutter.

Is it also possible to create a dynamic home page? For example when there will be no any card on the list it is going to write on the background there is no any card yet. But if card created this indication will be deleted.

Could you please support me regarding this topic?
