(pyqt6 python) How to get a signal when QListWidget's item is checked?

I made a list with QListWidget and add items from DB(about 100 or more items so check the flags with loop is hard)How can i check or get a signal when QListWidgetItem is checked?

Here is the code setting flags.

for data in DB:   item = QtWidgets.QListWidgetItem(self.list)   item.setText(str(data))   item.setFlags(item.falgs() | Qt.ItemFlag.ItemIsUserCheckable)   item.setCheckState(Qt.CheckState.Unchecked)

Using python ver 3.12, pyqt ver 6
