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() => 'GenerateInput[brief=$brief, channels=$channels, design=$design, doctype=$doctype, kind=$kind, model=$model, product=$product, project=$project, sourceMedia=$sourceMedia, title=$title, tone=$tone, voice=$voice]';
