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 'Signature{contentType: $contentType, acl: $acl, successActionStatus: $successActionStatus, policy: $policy, sign1: $sign1, sign2: $sign2, sign3: $sign3, sign4: $sign4, key: $key, bucket: $bucket}';
}
