 # Builders in Flutter Date Range Picker (SfDateRangePicker)

 The date range picker allows you to create a responsive UI with the conditions based on a widget’s details, and to design and create your custom view to the month cells and year cells in the date range picker.
 
 ## Cell builder
+
 The [DateRangePickerCellBuilder](https://pub.dev/documentation/syncfusion_flutter_datepicker/latest/datepicker/DateRangePickerCellBuilder.html) allows you to design your custom view and assign the view to the month and year view cells of the date range picker by returning an appropriate widget in the [cellBuilder](https://pub.dev/documentation/syncfusion_flutter_datepicker/latest/datepicker/SfDateRangePicker/cellBuilder.html) of [SfDateRangePicker](https://pub.dev/documentation/syncfusion_flutter_datepicker/latest/datepicker/SfDateRangePicker-class.html).
