how to add more than 24 hours in showtimepicker in flutter?

Question

I have a question about this this timePicker :

this is my code :

        final TimeOfDay? picked = await showTimePicker(
                  context: context,
                  initialTime: TimeOfDay.now(),
                  builder: (BuildContext context, Widget? child) {
                    return MediaQuery(
                      data: MediaQuery.of(context).copyWith(alwaysUse24HourFormat: true),
                      child: child ?? Container(),
                    );
                  },
                );

that works fine , but i want it to work as some kind of duration for something , so I want it to accept more than 24 hours ( i want user be able to select or add time less than 100 hours )

I tried some other packages but this one looks fine with ui and other stuffs , any hint ? thanks
