How to disable the input in the Flutter SfDateRangePicker?
In the Flutter date range picker, the user interaction can be disabled by using the selectableDayPredicate property of the date range picker.
STEP 1: In initState(), initialize the default values.
late List<DateTime> _activeDates;
final DateRangePickerController _controller = DateRangePickerController();
@override
void initState() {
DateTime today = DateTime.now();
today = DateTime(today.year, today.month, today.day);
_activeDates = [
today,
today.add(const Duration(days: 1)),
today.add(const Duration(days: 2)),
today.add(const Duration(days: 3)),
today.add(const Duration(days: 4)),
today.add(const Duration(days: 5)),
];
super.initState();
}
STEP 2: Set the selectionMode as range and set the initialSelectedRange. To make the disabled dates look as normal, the disabledDatesTextStyle is used.
child: SfDateRangePicker( controller: _controller, view: DateRangePickerView.month, selectionMode: DateRangePickerSelectionMode.range, initialSelectedRange: PickerDateRange(_activeDates[0], _activeDates[5]), startRangeSelectionColor: Colors.purple, endRangeSelectionColor: Colors.purple, rangeSelectionColor: Colors.purpleAccent, onSelectionChanged: selectionChanged, selectableDayPredicate: predicateCallback, monthCellStyle: const DateRangePickerMonthCellStyle( disabledDatesTextStyle: TextStyle( color: Colors.black87, fontSize: 13, fontFamily: 'Roboto')), ),
STEP 3: Using the selectableDayPredicate callback, set the specified dates for selection.
bool predicateCallback(DateTime date) {
for (int i = 0; i < _activeDates.length; i++) {
if (_activeDates[i] == date) {
return true;
}
}
return false;
}
STEP 4: Using selectionChanged callback, set the selected range of the picker as specified active dates.
void selectionChanged(DateRangePickerSelectionChangedArgs args) {
_controller.selectedRange =
PickerDateRange(_activeDates[0], _activeDates[5]);
}
