toString method
A string representation of this object.
Some classes have a default textual representation,
often paired with a static parse function (like int.parse).
These classes will provide the textual representation as
their string representation.
Other classes have no meaningful textual representation
that a program will care about.
Such classes will typically override toString to provide
useful information when inspecting the object,
mainly for debugging or logging.
Implementation
String toString() =>
"Calendar Event - eventId: $eventId, calendarId: $calendarId, title: $title, description: $description, start: $start, end: $end, all day: $allDay, location: $location, no. attendees: ${attendees!.length}";
