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() {
return 'Recommendation{'
'engineName: $engineName, '
'itemId: $itemId, '
'recommendationId: $recommendationId, '
'recommendationVariantId: $recommendationVariantId, '
'data: $data'
'}';
}
