manage_calendar_events

A Flutter plugin for reading, creating, updating, and deleting device calendar events — with reminders and attendees — on Android and iOS.

Platform support

Android	iOS
✓	✓

Features

• List all calendars available on the device, including whether each one is read-only or local
• Create and delete local (non-synced) calendars
• Read events from a calendar — all events, a date range, or a whole week/month
• Create and update events: title, description, location, URL, all-day flag, and a reminder
• Delete events
• Add, update, and delete reminders on an existing event
• Add, list, and remove attendees on an event

Getting started

1. Add the dependency

dependencies:
  manage_calendar_events: ^2.1.2

2. Android setup

Add the calendar permissions to android/app/src/main/AndroidManifest.xml:

<uses-permission android:name="android.permission.READ_CALENDAR" />
<uses-permission android:name="android.permission.WRITE_CALENDAR" />

3. iOS setup

Add the calendar usage description(s) to ios/Runner/Info.plist:

<key>NSCalendarsUsageDescription</key>
<string>This app needs calendar access to manage your events.</string>
<key>NSCalendarsFullAccessUsageDescription</key>
<string>This app needs calendar access to manage your events.</string>

NSCalendarsFullAccessUsageDescription is required on iOS 17+; NSCalendarsUsageDescription covers earlier versions.

Usage

import 'package:manage_calendar_events/manage_calendar_events.dart';

final _calendarPlugin = CalendarPlugin();

Request permissions

final granted = await _calendarPlugin.hasPermissions() ?? false;
if (!granted) {
  await _calendarPlugin.requestPermissions();
}

List calendars

final calendars = await _calendarPlugin.getCalendars();
final calendar = calendars!.first;

Create or delete a local calendar

final calendarId = await _calendarPlugin.createCalendar(
  calendarName: 'My App Calendar',
  color: Colors.blue,
);

// Only ever succeeds for a calendar created this way - it can't delete a
// user's real synced Google/iCloud calendar.
await _calendarPlugin.deleteCalendar(calendarId: calendarId!);

Read events

// Every event on a calendar
final events = await _calendarPlugin.getEvents(calendarId: calendar.id!);

// Events in an explicit date range
final events = await _calendarPlugin.getEventsByDateRange(
  calendarId: calendar.id!,
  startDate: DateTime.now(),
  endDate: DateTime.now().add(const Duration(days: 30)),
);

// Shortcuts for the current week / month
final weekEvents = await _calendarPlugin.getEventsByWeek(
  calendarId: calendar.id!,
  findDate: DateTime.now(),
);
final monthEvents = await _calendarPlugin.getEventsByMonth(
  calendarId: calendar.id!,
  findDate: DateTime.now(),
);

Create an event

final event = CalendarEvent(
  title: 'Team standup',
  description: 'Daily sync',
  startDate: DateTime.now(),
  endDate: DateTime.now().add(const Duration(hours: 1)),
  reminder: Reminder(minutes: 15), // remind 15 minutes before the event
);

final eventId = await _calendarPlugin.createEvent(
  calendarId: calendar.id!,
  event: event,
);

Update or delete an event

event
  ..eventId = eventId
  ..title = 'Team standup (moved)';
await _calendarPlugin.updateEvent(calendarId: calendar.id!, event: event);

await _calendarPlugin.deleteEvent(calendarId: calendar.id!, eventId: eventId!);

Reminders

await _calendarPlugin.addReminder(
  calendarId: calendar.id!,
  eventId: eventId!,
  minutes: 30,
);
await _calendarPlugin.updateReminder(
  calendarId: calendar.id!,
  eventId: eventId!,
  minutes: 10,
);
await _calendarPlugin.deleteReminder(eventId: eventId!);

Attendees

await _calendarPlugin.addAttendees(
  eventId: eventId!,
  newAttendees: [
    Attendee(name: 'Jane Doe', emailAddress: 'jane@example.com'),
  ],
);

final attendees = await _calendarPlugin.getAttendees(eventId: eventId!);
