stop watch timer on flutter. How can I print the time in the terminal while pressing a button?

Question

What I would like to do is printing the current time on the terminal while pressing the reset button.

ElevatedButton(
                onPressed: () {
                  _stopWatchTimer.onExecute.add(StopWatchExecute.reset);

                  setState(() {
                    showDialog(
                        barrierColor: Colors.black12.withOpacity(.6),
                    context: context,
                    builder: (_) {
                    return Dialog(
                    elevation: 0,
                    backgroundColor: Colors.transparent);
                    });
                  });

before the line _stopWatchTimer.onExecute.add(StopWatchExecute.reset); I would like to insert print() which would allow me to see the current time of my stopwatch timer on the terminal. The point is that I don't know what can I put inside the brackets of my print().

Into the class _MyAppState extends State<MyApp> , into the return Scaffold(...) I have a Streamibuilder where I have declared final value = snap.data; but I cannot access this variable "value" because the widget ElevatedButton is not within the StreamBuilder.

Thanks a lot for any kinf od help.
