CalendarBackend class abstract

A pluggable calendar backend. Implementations wrap caldav, device_calendar_plus, or an in-memory fake. All methods may throw; the fail-safe wrapping lives in UnicalClient, not here.

Task methods (listTasks/upsertTask/deleteTask) must throw UnsupportedError when capabilities().supportsVtodo is false.

Methods

capabilities() → Future<Capabilities>

Describes what this backend can preserve.

deleteEvent(String ref) → Future<void>

listEvents({DateTime? start, DateTime? end}) → Future<List<RemoteEvent>>

Lists events overlapping the optional [start, end) window.

listTasks() → Future<List<RemoteTask>>

Lists native VTODO tasks. Throws UnsupportedError if unsupported.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

upsertEvent(UnicalEvent event, {String? ref, Map<String, String> xProps}) → Future<String>

Creates or updates event. Pass ref to update an existing object and xProps to attach invisible metadata (ignored by backends that cannot preserve them). Returns the backend ref.

upsertTask(UnicalTask task, {String? ref}) → Future<String>

Creates or updates a native VTODO. Throws UnsupportedError if unsupported. Returns the backend ref.

Operators

operator ==(Object other) → bool

The equality operator.
