# calendar_view
[](https://github.com/SimformSolutionsPvtLtd/flutter_calendar_view/actions) [](https://pub.dev/packages/calendar_view)
A Flutter package allows you to easily implement all calendar UI and calendar
event functionality.
For web demo
visit [Calendar View Example](https://simformsolutionspvtltd.github.io/flutter_calendar_view/).
## Preview
## Installing
1. Add dependencies to `pubspec.yaml`
Get the latest version in the 'Installing' tab
on [pub.dev](https://pub.dev/packages/calendar_view/install)
```yaml
dependencies:
calendar_view:
```
2. Run pub get.
```shell
flutter pub get
```
3. Import package.
```dart
import 'package:calendar_view/calendar_view.dart';
```
## Implementation
1. Wrap `MaterialApp` with `CalendarControllerProvider` and
assign `EventController` to it.
```dart
CalendarControllerProvider(
controller: EventController(),
child: MaterialApp(
// Your initialization for material app.
),
)
```
2. Add calendar views.
For Month View
```dart
Scaffold(
body: MonthView(),
);
```
For Day View
```dart
Scaffold(
body: DayView(),
);
```
For Week view
```dart
Scaffold(
body: WeekView(),
);
```
For more info on properties
visit [documentation](https://pub.dev/documentation/calendar_view/latest/calendar_view/calendar_view-library.html)
.
3. Use `controller` to add or remove events.
To Add event:
```dart
final event = CalendarEventData(
date: DateTime(2021, 8, 10),
event: "Event 1",
);
CalendarControllerProvider.of(context).controller.add(event);
```
To Add events in range of dates:
```dart
final event = CalendarEventData(
date: DateTime(2021, 8, 10),
endDate: DateTime(2021,8,15),
event: "Event 1",
);
CalendarControllerProvider.of(context).controller.add(event);
```
To Remove event:
```dart
CalendarControllerProvider.of(context).controller.remove(event);
```
As soon as you add or remove events from the controller, it will
automatically update the
calendar view assigned to that controller.
See, [Use of EventController](#use-of-eventcontroller)
for more info
4. Use `GlobalKey` to change the page or jump to a specific page or date.
See, [Use of GlobalKey](#use-of-globalkey) for more info.

### Use of `EventController`
`EventController` is used to add or remove events from the calendar view. When
we add or remove
events from the controller, it will automatically update all the views to which
this controller is
assigned.
Methods provided by `EventController`
| Name | Parameters | Description |
|-----------------|--------------------------------------------------------------|-----------------------------------------------------------|
| add | CalendarEventData\ event | Adds one event in controller and rebuilds view. |
| addAll | List\\> events | Adds list of events in controller and rebuilds view. |
| remove | CalendarEventData\ event | Removes an event from controller and rebuilds view. |
| removeAll | List\\> events | Removes all event defined in the list |
| removeWhere | TestPredicate\\> test | Removes all events for which test returns true. |
| update | CalendarEventData\ event, CalendarEventData\ updated | Updates event with updated event. |
| getFullDayEvent | DateTime date | Returns the list of full day events stored in controller |
| updateFilter | EventFilter\ newFilter | Updates the event filter of the controller. |
| getEventsOnDay | DateTime date | Returns list of events on `date` |
Check [documentation](https://pub.dev/documentation/calendar_view/latest/calendar_view/EventController-class.html) for more info.
### Use of `GlobalKey`
User needs to define global keys to access functionalities like changing a page
or jump to a
specific page or date. Users can also access the `controller` assigned to
respected view using the
global key.
By assigning global keys to calendar views you can access methods and fields
defined by state class
of respected views.

### Synchronize events between calendar views
There are two ways to synchronize events between calendar views.
1. Provide the same `controller` object to all calendar views used in the
project.
2. Wrap MaterialApp with `CalendarControllerProvider` and provide controller as
argument as defined
in [Implementation](#implementation).
### Show only working days in WeekView.
You can configure week view such that it displays only specific days. ex,
```dart
WeekView(
weekDays: [
WeekDays.monday,
WeekDays.tuesday,
WeekDays.wednesday,
WeekDays.thursday,
WeekDays.friday,
],
);
```
Above code will create `WeekView` with only five days, from monday to friday.
