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() => 'License{license: $license, '
'status: $status, '
'charactersToCopyLeft: $charactersToCopyLeft, '
'pagesToPrintLeft: $pagesToPrintLeft, '
'canRenewLoan: $canRenewLoan, '
'maxRenewDate: $maxRenewDate, '
'canReturnPublication: $canReturnPublication}';
