Usage

Add day_picker to your pubspec.yaml file.

    flutter:
      sdk: flutter
    day_picker: 2.3.0

import the package:

import 'package:day_picker/day_picker.dart';

Constructor for the day_picker is given below.

      const SelectWeekDays({
        required this.onSelect,
        required this.days,
        this.backgroundColor,
        this.fontWeight,
        this.fontSize,
        this.selectedDaysFillColor,
        this.unselectedDaysFillColor,
        this.selectedDaysBorderColor,
        this.unselectedDaysBorderColor,
        this.selectedDayTextColor,
        this.unSelectedDayTextColor,
        this.border = true,
        this.boxDecoration,
        this.padding = 8.0,
        this.width,
        this.borderWidth,
        this.elevation = 2.0,
        super.key,
      });

Example here creates a day_picker with below style [with Gradient and no borders].

  final List<DayInWeek> _days = [
    DayInWeek("Zo", dayKey: "monday"),
    DayInWeek("Ma", dayKey: "tuesday"),
    DayInWeek("Di", dayKey: "wednesday"),
    DayInWeek("Wo", dayKey: "thursday"),
    DayInWeek("Do", dayKey: "friday"),
    DayInWeek("Vr", dayKey: "saturday", isSelected: true),
    DayInWeek("Za", dayKey: "sunday", isSelected: true),
  ];

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text("Select days in week"),
      ),
      body: Center(
        child: Padding(
          padding: const EdgeInsets.all(8.0),
          child: SelectWeekDays(
            key: customWidgetKey,
            fontSize: 14,
            fontWeight: FontWeight.w500,
            days: _days,
            border: false,
            width: MediaQuery.of(context).size.width / 1.4,
            boxDecoration: BoxDecoration(
              color: Colors.red,
              borderRadius: BorderRadius.circular(30.0),
            ),
            onSelect: (values) {
              print(values);
            },
          ),
        ),
      ),
    );
  }

Pass a callback to the onSelect property with parameter of type List<String>.

---

Pass a list of days of type DayInWeek into days property

class DayInWeek {
  DayInWeek(
      this.dayName, {
        required this.dayKey,
        this.isSelected = false,
      });

  String dayName;
  String dayKey;
  bool isSelected = false;
}

DayInWeek consist of three Properties [dayName], [dayKey] and [isSelected]. By default [isSelected] value will be false

---

Example:

void handleOnSelect(List<String> days){
    //TODO: Manipulate the List of days selected
    print(days);
}

Customization

Property	Type	Description
onSelect	List<String>	Callback invoked when days are selected
days	List<DayInWeek>	List of days that need to be passed
padding	double	Padding between container and the buttons [by default it is 8.0]
boxdecoration	BoxDecoration	provides variety of ways to style the background container[gradient, color, border radius]
backgroundColor	Color	Property to change the color of the container
fontSize	double	Property to change size of font
fontWeight	FontWeight	Property to change the font weight of text
daysFillColor	Color	Property to change the color of rounded buttons when the days are selected
daysBorderColor	Color	Property to change the border color of rounded button
selectedDayTextColor	Color	property to change the text color of the selected days
unSelectedDayTextColor	Color	property to change the text color when the days are not selected
border	bool	Set this property to false if border is not needed around the rounded buttons[by default this property will be true]

With the implementation of the setDaysState method, developers can dynamically modify which days are selected within their application's code, even after the SelectWeekDays widget has already been constructed. By utilizing the Global Key that is passed into the widget, one can easily update the selected dates as desired.
