Range selection using the multiple view picker in the Flutter Date Range Picker.
In the Flutter Date Range Picker, you can select the dates ranges from different pickers.
Step 1:
In initState(), set the default values for the date range picker.
@override
void initState() {
_dateRangePickerController = DateRangePickerController();
_dateRangePickerController2 = DateRangePickerController();
rangeStart = '';
rangeEnd = '';
super.initState();
}
Step 2:
Using the `onPressed` callback of the buttons, show the `AlertDialog` window and place the pickers inside the alert window. Set the `initialDisplayDate` for second picker.
child: FlatButton(
padding: const EdgeInsets.only(
left: 20, top: 10, right: 20, bottom: 10),
child: (rangeStart.isEmpty)
? const Text('Start Range')
: Text(
rangeStart,
),
onPressed: () {
showDialog(
context: context,
builder: (BuildContext context) {
return AlertDialog(
content: Container(
height: 300,
child: Column(children: <Widget>[
Row(
mainAxisAlignment:
MainAxisAlignment.spaceEvenly,
children: <Widget>[
getDateRangePicker(
_dateRangePickerController,
null),
getDateRangePicker(
_dateRangePickerController2,
DateTime(date.year,
date.month + 1, date.day)),
],
),
ButtonBarTheme(
child: ButtonBar(
children: <Widget>[
FlatButton(
child: Text(
'Cancel',
textAlign: TextAlign.right,
),
onPressed: () {
Navigator.pop(context, null);
},
),
FlatButton(
child: Text(
'Ok',
textAlign: TextAlign.right,
),
onPressed: () {
Navigator.pop(context);
setState(() {});
},
),
],
)),
])));
});
},
)),
Step 3:
Implement the Flutter calendar `onSelectionChanged` callback to get the selected ranges of the picker and using the `onPressed` event of the button, update selected ranges to button texts using the `DateRangePickerController` selectedRange property.
void selectionChanged(DateRangePickerSelectionChangedArgs args) {
if (args.value is PickerDateRange) {
rangeStart = DateFormat('dd MMMM, yyyy').format(args.value.startDate);
rangeEnd = args.value.endDate == null
? rangeStart
: DateFormat('dd MMMM, yyyy').format(args.value.endDate);
_dateRangePickerController2.selectedRange =
PickerDateRange(args.value.startDate, args.value.endDate);
_dateRangePickerController.selectedRange =
PickerDateRange(args.value.startDate, args.value.endDate);
}
SchedulerBinding.instance.addPostFrameCallback((duration) {
});
}
