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
@override
String toString() => 'EventsBase(eventType: $eventType'
'${timestamp == null ? '' : ', timestamp: $timestamp'}'
'${userId == null ? '' : ', userId: $userId'}'
'${barcode == null ? '' : ', barcode: $barcode'}'
'${points == null ? '' : ', points: $points'}'
')';
