how to set default date to first Sat after today in flutter

seems to work fine As I conclude from your question, here are your requirements :
how to :

  bool defineSelectable(DateTime val) {
    DateTime now = DateTime.now();
    // disabled all days before today
    if (val.isBefore(now)) {
      return false;
    }
    // disabled all days except Sats
    switch (val.weekday) {
      case saturday:
        return true;
        break;
      default:
        return false;
    }
  }

  void handleButton(context) async {
    DateTime chosenDate = await showDatePicker(
      ...
      selectableDayPredicate: defineSelectable,
    );
  }

  int daysToAdd(int todayIndex, int targetIndex) {
    if (todayIndex < targetIndex) { // jump to target day in same week
      return targetIndex - todayIndex;
    } else if (todayIndex > targetIndex) { // must jump to next week
      return 7 + targetIndex - todayIndex;
    } else {
      return 0; // date is matched
    }
  }

  DateTime defineInitialDate() {
    DateTime now = DateTime.now();
    int dayOffset = daysToAdd(now.weekday, saturday);
    return now.add(Duration(days: dayOffset));
  }

  void handleButton(context) async {
    DateTime chosenDate = await showDatePicker(
      ...
      initialDate: defineInitialDate(),
      ...
    );
  }

How do I change a DatePickerDialog's default date from today's date to a user selected date?

Any of those help When the user picks the date, use the following to communicate the data back to your Activity once the dialog closes (communicating data from a fragment back to the starting activity): http://developer.android.com/training/basics/fragments/communicating.html
Once you receive the values back in your activity, use the following when starting your DatePickerFragment:
DatePickerFragment datepickerfragment = new DatePickFragment();

Bundle bundle = new Bundle();
bundle.putInt("YEAR", currentyear);
bundle.putInt("MONTH", currentmonth);
bundle.putInt("DAY", currentday);
datepickerfragment.Arguments = bundle;

fragmentmanager.BeginTransaction().Add(R.layout.container, datepickerfragment).Commit();
int year = this.Arguments.getInt("YEAR");
int month = this.Arguments.getInt("MONTH");
int day = this.Arguments.getInt("DAY");
....
int year = this.Arguments.getInt("YEAR");
int month = this.Arguments.getInt("MONTH");
int day = this.Arguments.getInt("DAY");

if(year != null){
    return new DatePickerDialog(getActivity(), this, year, month, day);
}else{
    final Calendar c = Calendar.getInstance();
    year = c.get(Calendar.YEAR);
    month = c.get(Calendar.MONTH);
    day = c.get(Calendar.DAY_OF_MONTH);
    return new DatePickerDialog(getActivity(), this, year, month, day);
}

Flutter - DatePicker is not opening if it is same date(today)


Tag : android , By : Vrki

I wish this help you Here is the solution You need to make defineSelectable function return true on initialDate you are passing. See the working code below
DateTime selectedDate = DateTime.now();
DateTime initialData;

bool defineSelectable(DateTime val) {
DateTime now = DateTime.now();
//make it return true on initialDate
if(val.compareTo(initialData)==0){
return true;
}
// disabled all days before today
if (val.isBefore(now)) {
return false;
}
// disabled all days except Friday
switch (val.weekday) {
case DateTime.friday:
  return true;
  break;
default:
  return false;
}
}

int daysToAdd(int todayIndex, int targetIndex) {
print('todayIndex $todayIndex');
print('targetIndex $targetIndex');
if (todayIndex < targetIndex) { // jump to target day in same 
week
return targetIndex - todayIndex;
} else if (todayIndex > targetIndex) { // must jump to next 
week
return 7 + targetIndex - todayIndex;
} else {
return 0; // date is matched
}
}

DateTime defineInitialDate() {
DateTime now = DateTime.now();
int dayOffset = daysToAdd(now.weekday, DateTime.friday);
print('dayOffset: $dayOffset');
return now.add(Duration(days: dayOffset));
}

Future<Null> _selectDate(BuildContext context) async {
initialData = defineInitialDate();
print('defineInitialDate: ${initialData}');
print('defineSelectable: $defineSelectable');
final DateTime picked = await showDatePicker(
  context: context,
  initialDate: initialData,
  selectableDayPredicate: defineSelectable,
  firstDate: DateTime(2018, 12),
  lastDate: DateTime(2020, 12));
if (picked != null && picked != selectedDate) selectedDate = 
picked;
//var formatter = DateFormat('EEEE, dd-MMMM-yyyy');
//String formatted = formatter.format(selectedDate);
print('Select Date: $selectedDate');
//_askGiveProvider.meetingSink(formatted);
//addEventBloc.eventDateSink(formatted);
}
