void initState() {
_focusedDay = DateTime.now();
super.initState();

}

focusedDay: _focusedDay,
rowHeight: 45,
calendarFormat: _calendarFormat,
startingDayOfWeek: StartingDayOfWeek.monday,
selectedDayPredicate: (day) {
return isSameDay(_selectedDay, day);
},
onDaySelected: (selectedDay, focusedDay) {
print("selected date is " + selectedDay.toString());
var dayOfWeek = DateFormat.EEEE().format(selectedDay);
// widget.foodDateSelectionCallback.onFoodDateSelected(
// selectedDay.toString().split(" ")[0], dayOfWeek);
// Navigator.pop(context);

                    if (!isSameDay(_selectedDay, selectedDay)) {

error isSameDat(focusday,lastday)|| focusday.isBefore(lastDay) is not true

Looks like your _focusedDay is after your lastDay. It has to be between the firstDay and the lastDay in order for the widget to work properly.
