Date Range Picker 📅

Date Range Picker is a user-friendly and simple package for Flutter that allows users to select a date range. It's designed to evolve over time, and its components are built to be reusable.

(Isn't it beautiful?)

Features ✅

• Simple and user-friendly interface
• Customizable theme
• Reusable components
• Field, form field, and dialog widgets
• Functions to display a date range picker as a dialog
• Supports minimum and maximum date limitations
• Displays two months at once for easy navigation

Installation 🪛

Add the package to your pubspec.yaml file:

dependencies:
  date_range_picker: ^latest_version

Then, run flutter packages get in your terminal.

Usage 📖

To use the Date Range Picker, simply import the package and create a DateRangePickerWidget:

DateRangePickerWidget(
    doubleMonth: doubleMonth,
    maximumDateRangeLength: 10,
    minimumDateRangeLength: 3,
    initialDateRange: selectedDateRange,
    disabledDates: [DateTime(2023, 11, 20)],
    initialDisplayedDate:
    selectedDateRange?.start ?? DateTime(2023, 11, 20),
    onDateRangeChanged: onDateRangeChanged,
);

You can also use the DateRangeField or DateRangeFormField to display a dialog asking the user to select a date range, and to display the selected range. Here is an example:

DateRangeField(
    decoration: InputDecoration(
        label: Text("Date range picker"),
        hintText: 'Please select a date range',
    ),
    onDateRangeSelected: (DateRange? value) {
    // Handle the selected date range here
    },
  selectedDateRange: selectedRange,
);

Lastly, you can use the showDateRangePickerDialog function to display a dialog asking the user to select a date range:

showDateRangePickerDialog(
    context: context, 
    builder: datePickerBuilder
);
...

Widget datePickerBuilder(BuildContext context, dynamic Function(DateRange) onDateRangeChanged) => DateRangePickerWidget(
    doubleMonth: true,
    initialDateRange: selectedDateRange,
    onDateRangeChanged: onDateRangeChanged,
);

Customization 🎨

You can customize the appearance of the Date Range Picker by providing a custom CalendarTheme:

DateRangePickerWidget(
    onDateRangeChanged: (dateRange) {
    // Handle the selected dateRange here
    },
    theme: CalendarTheme(
    selectedColor: Colors.blue,
    dayNameTextStyle: TextStyle(color: Colors.black45, fontSize: 10),
    inRangeColor: Color(0xFFD9EDFA),
    inRangeTextStyle: TextStyle(color: Colors.blue),
    selectedTextStyle: TextStyle(color: Colors.white),
    todayTextStyle: TextStyle(fontWeight: FontWeight.bold),
    defaultTextStyle: TextStyle(color: Colors.black, fontSize: 12),
    radius: 10,
    tileSize: 40,
    disabledTextStyle: TextStyle(color: Colors.grey),
    )
,
);
