How to get the current view dates in the Flutter Date Range Picker (SfDateRangePicker)?

In Flutter Date Range Picker, you can get the current month start and end dates using the `onViewChanged` callback.

Step 1:

Inside the state, initialize the controller for the date range picker and set the default values for start and end date of the current month.

final DateRangePickerController _controller = DateRangePickerController();
String _startDate = '', _endDate = '';

Step 2:

Place the date picker inside the body of the Scaffold widget and trigger the `onViewChanged` callback of the date picker.

body: Column(
  children: <Widget>[
    Container( height:50,
        child: Text('StartDate:''$_startDate')),
    Container(height:50
        ,child: Text('EndDate:''$_endDate')),
    Card(
      margin: const EdgeInsets.fromLTRB(40, 100, 50, 40),
      child: SfDateRangePicker(
        controller: _controller,
        view: DateRangePickerView.month,
        onViewChanged: viewChanged,
      ),
    )
  ],
),

Step 3:

Using the `onViewChanged` callback of the date picker get the start and dates of the current month.

void viewChanged(DateRangePickerViewChangedArgs args) {
 
    _startDate = DateFormat('dd, MMMM yyyy')
        .format(args.visibleDateRange.startDate!)
        .toString();
    _endDate=DateFormat('dd, MMMM yyyy')
        .format(args.visibleDateRange.endDate!)
        .toString();
    SchedulerBinding.instance!.addPostFrameCallback((duration) {
      setState(() {});
    });
}
