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 'AdImpression('
'adType: $adType, '
'cpm: $cpm, '
'network: $network, '
'priceAccuracy: $priceAccuracy, '
'versionInfo: $versionInfo, '
'creativeIdentifier: $creativeIdentifier, '
'identifier: $identifier, '
'impressionDepth: $impressionDepth, '
'lifetimeRevenue: $lifetimeRevenue)';
}
