toString method
override
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
// When adding new fields, ensure we don't go over the maximum length (100).
// Current length:
// 13 - nyxx_commands prefix
// 4 - / separators
// 6 - uniqueIdentifier (assume we won't go over 1 000 000 interactions in one session)
// 27 - sessionStartTime
// 27 - expiresAt
// 19 - allowedUser
// Total: 96, 4 free (could be used up by uniqueIdentifier)
// TODO: Serialize to binary => encode base64?
String toString() => 'nyxx_commands/$uniqueIdentifier/$sessionStartTime/$expiresAt/$allowedUser';
