+# How to customize the month cell of the Flutter date range picker (SfDateRangePicker)?
+
+In the flutter date range picker, you can customize the month cells by using the `specialDates`, `blackoutDates`, and `showTrailingAndLeadingDates` properties.
+
+## Step 1:
+In initState(), set the default dates for special, blackout dates, and set the default color values for the weekend days, special dates, current date, blackout dates, leading and trailing dates.
+
+```xml
+DateRangePickerController _controller;
+List<DateTime> _blackoutDates;
+List<DateTime> _specialDates;
+Color weekEndColor,
+    specialDatesColor,
+    todayColor,
+    leadingTrailingDatesColor,
+    blackoutDatesColor;
+ 
+@override
+void initState() {
+  // TODO: implement initState
+  _controller = DateRangePickerController();
+  _blackoutDates = _getBlackoutDates();
+  _specialDates = _getSpecialDates();
+  weekEndColor = Color(0xFF0e9aa7);
+  leadingTrailingDatesColor = Color(0xFF88d8b0);
+  specialDatesColor = Color(0xFFf6cd61);
+  todayColor = Color(0xFFff6f69);
+  blackoutDatesColor = Colors.black;
+  super.initState();
+}
+```
+ 
+
+## Step 2:
+Place the calendar inside the body of the Scaffold widget. Using the `TextStyle` and `BoxDecoration` widget you can customize the dates with shapes and colors. In the same way, you can also customize the blackout dates.
+
+```xml
+body: Card(
+  margin: const EdgeInsets.fromLTRB(40, 150, 40, 150),
+  child: SfDateRangePicker(
+    view: DateRangePickerView.month,
+    monthViewSettings: DateRangePickerMonthViewSettings(
+        specialDates: _specialDates,
+        showTrailingAndLeadingDates: true,
+        blackoutDates: _blackoutDates),
+    monthCellStyle: DateRangePickerMonthCellStyle(
+        blackoutDateTextStyle: TextStyle(
+            color: blackoutDatesColor,
+            decoration: TextDecoration.lineThrough),
+        specialDatesDecoration: BoxDecoration(
+            shape: BoxShape.circle,
+            border: Border.all(width: 1),
+            color: specialDatesColor),
+        specialDatesTextStyle: TextStyle(color: Colors.black),
+        cellDecoration: BoxDecoration(shape: BoxShape.circle),
+        selectionColor: Color(0xFFf8dbdff),
+        todayTextStyle: TextStyle(color: Colors.white),
+        todayCellDecoration:
+            BoxDecoration(shape: BoxShape.circle, color: todayColor),
+        weekendDatesDecoration: BoxDecoration(
+            color: weekEndColor,
+            border: Border.all(width: 1),
+            shape: BoxShape.circle),
+        trailingDatesDecoration: BoxDecoration(
+            shape: BoxShape.rectangle, color: leadingTrailingDatesColor),
+        leadingDatesDecoration: BoxDecoration(
+            shape: BoxShape.rectangle, color: leadingTrailingDatesColor)),
+    todayHighlightColor: Colors.orange,
+  ),
+));
+```
