New Pull Request for #400, related to #298

Currently working in example:

• [x] can build daily or weekly recurring events.
• [x] can build monthly or yearly events.
• [x] can build complex (eg. multi days a week) events.
• [x] can delete all events in the chain.
• [x] can delete single events.
• [x] can delete this and following instances

Hurdles (all should be solved before merge):

• [x] rrule changes are published.
• [x] most features are working / non-working features hidden and labeled.
• [x] re-enable lower API support (full or partial), or document why they should be dropped.

Reported issue: 'the property "Event.allDay = true;" doesn't save the event correctly in the calendar.'

Further comments: this appears to be an issue on Android based on the timezone of the event (eg setting an all day event with a start day before 11am AEST results in the event being for the previous day)

Related to #344

Somehow the latest dependency upgrade is not working here. It seems that the flutter used within the server was and old version.

We may need to upgrade the current azure pipeline, or maybe switch to github action?

device_calendar does not specify a Swift version and none of the targets (Runner) integrating it have the SWIFT_VERSION attribute set. Please contact the author or set the SWIFT_VERSION attribute in at least one of the targets that integrate this pod.

After updating dependencies and running dart migrate, and with a few manual patches, this is the kind-of functional null safety enabled device_calendar.

Tested and working functions (because I use them):

• [x] retrieveCalendars() retrieves calendar on Android
• [x] Event event(calendarId_String) can be set correctly (although I still find it confusing to use a number as a string)
• [x] createOrUpdateEvent() added calendar event to the selected calendar

If anyone is interested please test it with other functions and see if they run, and better yet, help fixing other bugs.

To use this instead of the published package:

1. Save it to somewhere convenient, like next to your app package:

Parent Folder ├YourApp └device_calendar_null

2. add this to your pubspec.yaml

dependencies:

device_calendar:

path: ../device_calendar/

3. Run flutter pub get

hey I am using the latest version in flutter app, trying to create an event. I see that the code return success, but when I go into the calendar, I see that event is not created. I would really appreciate any pointers as to why I am not seeing events in the calendar.

in a code I am setting the calendar in a method, and calling another method to create the event.

       calendarsResult = await _deviceCalendarPlugin.retrieveCalendars();
       setState(() {
        _selectedCalendar = calendarsResult?.data[0];
        _addEventsToCalendar(_academicEvents);
       });

Future _addEventsToCalendar(List<AcademicEvent> events) async {
    if (_selectedCalendar != null) {
     if (events != null && events.length > 1) {
       for (var event in events) {
      final eventTime = new DateTime(event.eventStartDate.year, event.eventStartDate.month,   event.eventStartDate.day);
      final eventToCreate = new Event(_selectedCalendar.id);
      eventToCreate.title = event.eventSummary;
      eventToCreate.start = eventTime;
      eventToCreate.description = event.eventSummary;
      ;
      String eventId = event.eventUID.toString();
      if (eventId != null) {
        eventToCreate.eventId = eventId;
      }
      eventToCreate.end = new DateTime(DateFormat.yMMMd().format(eventStartDate));
      final createEventResult =
          await _deviceCalendarPlugin.createOrUpdateEvent(eventToCreate);
      if (createEventResult.isSuccess &&
          (createEventResult.data?.isNotEmpty ?? false)) {
        //print("events added to local calander");
      }
    }
  }
}

I am trying to add calendar event to google pixel phone. But i am not able to add it and i couldn't find Default calendar (My Calendar) in calendar app also.
Is there any thing i need to setup in my app to work with google pixel phones?

one more issue is like, i am not able to set "Timezone" while creating event.

I have been gotten issue with retrieveCalendars when build release.

If I build project by code, device_calendar work well. But if I build release apk and then install by generated apk. this method cannot retrieveCalendars on device.

Please help me about this.

Thanks

Part of #346

Appearantly our publish credentials are expired since March. That's why our action stuck in a loop.

Also see https://github.com/sakebook/actions-flutter-pub-publisher/issues/22

I think @nickrandolph need to get a new one from pub.dev

Why: It seems that the V2 embedding was not applied to the plugin file, Just to the manifest.

What: This PR adds support for v2 embedding.

Documentation:

#326

Only on Android (IOS is working fine, same code), I'm getting back a non-empty array with the right amount of calendars (length 2), but the actual fields are all null, (id, name etc..) any ideas? permissions are granted correctly, I tried both on the simulator and on a real device

final calendarsResult = await _deviceCalendarPlugin.retrieveCalendars();

I am running flutter application in Android devices, when i am creating an event in flutter application then it is also visible on Google Calendar with all details that i added in flutter application using createOrUpdateEvent() method. But the problem is that when i updating an already created event's details( title, description, location, start date and end date ) in flutter application then it is not updating in Google Calendar. I am also not receiving any exception or error in debug mode while updating details.

I am facing this issue in almost android devices. But in some android devices(like Samsung Galaxy M10) when i am updating details(title, start date etc.) then these details are also changing in Google Calendar.

Working correct in following devices:-

1. Samsung Galaxy M10
2. Redmi 11

Not working in following devices:-

1. Redmi Note 9
2. Motorola e5 plus
3. Samsung galaxy on next

I am using device_calendar latest version that is ^4.2.0

I have modified from iOS Source Code and make it work in macOS.

What I have changed:

• Reuse model attendee from iOS. (dart file)
• Update Plugin configuration.
• Modified DeviceCalendarPlugin swift file, I think we can re-use if some one has more exprience in Swift (not by me)

• Remove UIKit, EventKitUI (only supported in iOS).
• Remove show event detail in modal by iOS (macOS does not has UIKit).
• Migrate from UIColor -> NSColor (supported by macOS)

For the future, I think we can conduct code in Swift and find the extension for support both iOS and macOS.

Feel free ask me if you want to do anything.

Notes:

• Please add this into Info.plist

	<key>NSCalendarsUsageDescription</key>
	<string>Access most functions for calendar viewing and editing.</string>

• Also, add this into entitlement file

	<key>com.apple.security.personal-information.calendars</key>
	<true/>

In-case you run code for checking, please run by command-line instead of dirrectly from VS code or Android Studio, I think that bug from Flutter.

flutter run -d macos

Tthe current Swift-implentation of requestPermissions does not return if permissions have already been granted. Thus, if it is called more than once, subsequent attempts try to request permissions again, causing the call to fail with a 400-error (To create or update an all day event you must provide calendar ID, event with a title and event's start date).

There was already a second implementation of requestPermissions which wasn't used anywhere but correctly short-circuits if permissions have already been granted so I thought it would be better to use that.

EDIT: Actually, the errors seem to be caused by an error on my end. Regardless, this change seems reasonable to me, if less urgent :)

I have integrated the device calendar plugin in my project and all the functions are working fine when I run the code but when I run it in release mode or make a built to release, these functionalities are not working

Hi,

Flutter pub get outputs some warnings about device_calendar :

The plugin `device_calendar` uses a deprecated version of the Android embedding.
To avoid unexpected runtime failures, or future build failures, try to see if this plugin supports the Android V2 embedding. Otherwise, consider removing it since a future
release of Flutter will remove these deprecated APIs.
If you are plugin author, take a look at the docs for migrating the plugin to the V2 embedding: https://flutter.dev/go/android-plugin-migration.

And app build fails for Android :

e: [...]snap/flutter/common/flutter/.pub-cache/hosted/pub.dartlang.org/device_calendar-3.9.0/android/src/main/kotlin/com/builttoroam/devicecalendar/CalendarDelegate.kt: (674, 36): Only safe (?.) or non-null asserted (!!.) calls are allowed on a nullable receiver of type Activity?

FAILURE: Build failed with an exception.
