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('
'adUnit: $adUnit, '
'adSdkName: $adSdkName, '
'adNetwork: $adNetwork, '
'placement: $placement, '
'testGroup: $testGroup, '
'segmentName: $segmentName, '
'instanceName: $instanceName, '
'bundleId: $bundleId, '
'revenue: $revenue)';
}
