device_calendar_plus 0.7.1

A modern, maintained Flutter plugin for reading and writing device calendar events on Android and iOS.

0.7.1 - 2026-06-17

Changed

• Add the device pub.dev topic (dropped federated to stay within the five-topic limit).

Docs

• Slimmed the README to an overview plus a getting-started snippet, and moved the worked examples into focused topic guides under doc/. Trimmed the API doc comments to the consumer-facing contract and removed native-API implementation details. No code or behavior changes.

0.7.0 - 2026-06-17

Added

• Write-only calendar access. requestPermissions(level: CalendarAccessLevel.writeOnly) asks for the gentler add-only prompt and a grant reports CalendarPermissionStatus.writeOnly. On iOS this is not a permanent ceiling — a later full request re-prompts and upgrades the app in-app (#89).
• Automatic permission handling. Set DeviceCalendar.instance.autoPermissions to AutoPermissionMode.asNeeded or .full and methods request the access they need on first use instead of throwing when permission is undetermined (#90).
• createEvent's calendarId is now optional — omit it to write to the platform's default calendar (iOS defaultCalendarForNewEvents, Android the primary or first writable calendar). Resolving the default on Android reads the calendar list, so that path needs full access (#88).
• Event reminders. createEvent takes reminders: List<Duration>, updateEvent takes Patch<List<Duration>>, and Event.reminders is read back. Relative before-start offsets, normalized to whole minutes on both platforms (#87).

0.6.0 - 2026-06-16

Changed

• Breaking: updateRecurring() now takes start: DateTime instead of startTime: EventTimeOfDay. start is the anchored occurrence's new start; the whole scope translates by the wall-clock delta, so a single call can move the time and the day together — a nightshift 11 PM → 1 AM (crosses midnight) or a weekly meeting Monday → Tuesday. The delta is measured in the event's timezone, so it is DST-safe. (#103, thanks @SuperKrallan)
• Breaking: EventTimeOfDay is removed.
• Breaking: all-day events now accept start (only its date is used) instead of throwing.

Added

• updateRecurring() translates implicit-day rules for free: a WeeklyRecurrence() / MonthlyRecurrence() with no pinned day follows the anchor when you move the day.

Behaviour

• Moving the day of a rule that pins it explicitly (daysOfWeek, daysOfMonth, positional) without also passing a recurrenceRule throws DeviceCalendarException(invalidArguments). Moving one day of a multi-day rule is genuinely ambiguous (Mon of Mon/Wed/Fri → Tue could mean Tue/Wed/Fri or Tue/Thu/Sat), so the API hands the decision back to you. Time-only, duration-only and whole-week shifts never throw.

0.5.2 - 2026-06-15

Changed

• No-op updates are now valid instead of throwing. updateEvent, updateRecurring and updateCalendar return without a platform write when no fields are provided, so "save with no edits" is a harmless no-op rather than an ArgumentError (#95). updateRecurring returns the targeted scope's event id. updateRecurring's duration now accepts zero (an instantaneous event); only a negative duration is rejected.

Fixed

• Recurrence parsing accepts a negative BYMONTHDAY (e.g. -1 for the last day of the month) instead of rejecting the rule (#91)
• Turning a recurring occurrence non-recurring with thisAndFollowing + Patch.clear() now splits the series on iOS instead of collapsing the whole series into one event (#93) — see the device_calendar_plus_ios changelog
• listEvents returns every event across spans longer than ~4 years without dropping or duplicating recurring instances (iOS, #94), and includes zero-duration events sitting exactly on the query start (Android, #416) — see the platform changelogs
• createCalendar fails with a clear error on iOS sources that can't hold calendars, instead of an opaque failure (#96) — see the device_calendar_plus_ios changelog
• iOS EventKit operations run off the main thread, preventing UI stalls on large calendars (#79) — see the device_calendar_plus_ios changelog

Docs

• Documented listEvents per-instance expansion and the eventId@timestamp instanceId format (#97)

0.5.1 - 2026-06-15

Fixed

• iOS: showEventModal(edit: true) no longer crashes (#77) — see the device_calendar_plus_ios 0.5.1 changelog

Docs

• Clarified showEventModal docs: the view modal (edit: false) is not read-only — on both iOS and Android the native screen lets the user edit the event, and those edits are saved directly by the OS

0.5.0 - 2026-06-11

Changed

• Breaking: updateRecurring() is redesigned around series semantics (#69). Times are now expressed as startTime (EventTimeOfDay) plus duration instead of absolute startDate/endDate, so every occurrence keeps its own date — changing a series' time no longer re-anchors the series to the occurrence you happened to edit (#68, thanks @SuperKrallan). The recurrence rule is now a Patch<RecurrenceRule>: Patch.set replaces it, Patch.clear collapses the series into a single event. Returns the event ID of the affected scope.
• Breaking: EventSpan.thisInstance is gone — EventSpan is now just allEvents and thisAndFollowing. Single occurrences are handled by updateEvent / deleteEvent with an instance ID (below).
• Breaking: updateEvent() with an instance ID (eventId@timestamp) edits only that occurrence, detaching it from the series; a bare event ID on a recurring event updates the whole series.
• Breaking: deleteEvent() with an instance ID removes only that occurrence; a bare event ID deletes the event (the whole series when recurring).

Added

• EventTimeOfDay — small validating hour/minute value class used by updateRecurring().

Fixed

• Occurrence edits with a startDate past the occurrence's untouched end are rejected with invalidArguments on iOS too, matching Android, instead of saving an inverted event.
• Android: events with no status read back as EventStatus.none instead of EventStatus.tentative — thanks @mauriziopinotti (#70).
• Android: all Calendar Provider work runs on a background thread; large calendars could ANR — thanks @mauriziopinotti (#73).

0.4.0 - 2026-05-25

Added

• updateRecurring() — update a recurring event with a span choice: EventSpan.allEvents (whole series), thisAndFollowing (this occurrence and every later one), or thisInstance (only this occurrence). Can change or remove the recurrence rule. Resolves the long-standing limitation that updateEvent() could not edit recurrence. Based on @SuperKrallan (#36)
• deleteRecurring() — delete part of a recurring event with a span choice: EventSpan.allEvents (whole series), thisAndFollowing (this occurrence and every later one), or thisInstance (only this occurrence). Now supported on both iOS and Android (Android uses EXDATE on the master rather than a cancelled exception event). Based on @SuperKrallan (#43)
• EventSpan enum for choosing the scope of a recurring-event operation, shared by updateRecurring() and deleteRecurring()
• url parameter on updateEvent() — based on @SuperKrallan (#38)
• edit parameter on showEventModal() — when true, opens the native editor directly (EKEventEditViewController on iOS, ACTION_EDIT on Android) instead of the read-only viewer. Based on @xonaman (#45)
• Calendar.color getter — derived Flutter Color? parsed from colorHex, saving consumers from writing the same hex-parsing helper. Based on @xonaman (#46)

Changed

• Breaking: updateEvent() description, location and url now take a Patch<String> instead of a String. null leaves the field unchanged, Patch.set(value) assigns a value, Patch.clear() removes it — clearing an optional field was previously impossible.

Fixed

• Missing availability parameter in platform interface test mock — based on @SuperKrallan (#39)

0.3.5 - 2026-04-20

Added

• listSources() to discover calendar accounts/sources — based on @magic-fit (#14)
• Source selection on createCalendar — iOS via CreateCalendarOptionsIos(sourceId:), Android via optional accountType
• supportsCalendarCreation on CalendarSource
• availability parameter on updateEvent() — thanks @SuperKrallan (#29)
• url field on events (iOS: EKEvent.url, Android: CUSTOM_APP_URI) — thanks @magic-fit (#32)
• showCreateEventModal() with optional pre-fill (title, dates, location, description)
• Read-only attendees on events (name, email, role, status)

Fixed

• Android: all-day events appearing in wrong day's query in non-UTC timezones (#20)
• Android: hasPermissions() now works from background services without an Activity (#31)
• Android: calendar/event queries use application context for background compatibility — thanks @vitalii-vov (#26)
• Android: notDetermined permission status correctly distinguished from denied — thanks @Albert221 (#12)
• iOS: calendar source lookup fallback when default source is unavailable — thanks @zaqwery (#13)
• iOS: createCalendar default fallback now picks iCloud over Gmail CalDAV (#33)

0.3.4 - 2026-02-08

Added

• iOS: Swift Package Manager support

0.3.3 - 2025-12-21

Fixed

• Fixed parsing of instanceId for events with @ in their event ID (e.g., Google Calendar IDs like [e-mail])

0.3.2 - 2025-12-19

Added

• Android: CreateCalendarOptionsAndroid for specifying custom account name when creating calendars
• createCalendar() now accepts optional platformOptions parameter for platform-specific configuration

0.3.1 - 2025-11-07

Fixed

• showEventModal() now properly awaits until the modal is dismissed (iOS and Android)

0.3.0 - 2024-11-05

Changed

• BREAKING: deleteEvent() now requires named parameter eventId and always deletes entire series for recurring events
• BREAKING: updateEvent() now uses named parameter eventId (renamed from instanceId) and always updates entire series for recurring events
• BREAKING: Removed deleteAllInstances and updateAllInstances parameters - operations on recurring events now always affect the entire series
• Renamed getEvent() and showEventModal() parameter from instanceId to id to clarify that both event IDs and instance IDs are accepted

Removed

• BREAKING: NOT_SUPPORTED error code (no longer needed)

0.2.0 - 2024-11-05

Added

• openAppSettings() method to guide users to system settings when permissions are denied
