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 'KeyValueErrorContext('
'statusCode: ${statusCode?.name}, '
'opaque: $opaque, '
'cas: $cas, '
'key: $key, '
'context: $context, '
'ref: $ref'
')';
}
