Flutter package for custom AppBar with calendar view.

The package is currently optimized for mobile devices, therefore used only for mobile devices is prefered. It also works for larger screens, although it does not follow the rules of good UI. It is planned to be optimized shortly.

Features #

  • Define your custom color scheme
  • Enable or disable full-screen calendar view
  • Provide a list of dates that will be marked on the calendar view
  • Manipulate with a range of displayed dates

Installation and Basic Usage #

Add to pubspec.yaml:

dependencies:
  calendar_appbar: ^0.0.1

Then import it to your project:

import 'package:calendar_appbar/calendar_appbar.dart';

Finaly add CalendarAppBar in Scaffold:

@override
Widget build(BuildContext context) {
  return Scaffold(
      appBar: CalendarAppBar(
        onDateChanged: (value) => print(value),
        firstDate: DateTime.now().subtract(Duration(days: 140)),
        lastDate: DateTime.now(),
      ),
    );
}

There are three required attributes of class CalendarAppBar. Attribute onDateChange is a function, which defines what happens when the user selects a date. firstDate attribute defines the first date, which will be available for selection. The date saved in lastDate attribute is the last date available for selection. At first initialization of the object, the date provided as lastDate will be selected, but will not be returned with onDateChange function.

More Custom Usage #

Hide Full Screen Calendar View #

This package enables the usage of a full-screen calendar view. It is displayed when the user presses on month and year text in the top right corner of the AppBar. It comes in two different versions. If the first and last date are part of the same month the full-screen calendar will be displayed as seen on the third image at the top of this file. In the other way, it will be displayed as seen in the second image. It is possible to disable the full-screen view (which is enabled by default) by adding the following code:

    fullCalendar: false,

Define Your Custom Color Scheme #

You can define your custom color scheme by defining white, black and accent color. Those three colors are set to Colors.white, Colors.black87 and Color(0xFF0039D9) by default. It is possible to customize those three colors as shown below.

    white: Colors.white,
    black: Colors.black,
    accent: Colors.blue,

The design is currently optimized for light mode and therefore also suggested to be used in that way to achieve better UX. Dark mode will be added soon.

Custom Padding #

The horizontal padding can be customized (default it is set to 25px) by adding the following code:

    padding: 10.0,

Mark Dates with Events #

It is possible to provide the list of dates of type List<DateTime>, which will be marked on calendar view with a dot.

    events: List.generate(
            10, (index) => DateTime.now().subtract(Duration(days: index * 2))),

The code above will generate the list of 10 dates for every second day from today backwards.

Back Button #

The last attribute of CalendarAppbar is backButton, which is default set to true. Customize that feature by setting this attribute to false.

    backButton: false,
