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() {
var str = '{readerName: $readerName';
for (final tokenInfo in tokens) {
str += ', {';
str += 'tokenId: ${tokenInfo.tokenId}';
(tokenInfo.slotName != null) ? str += ', slotName: ${tokenInfo.slotName}' : null;
(tokenInfo.driverName != null) ? str += ', driverName: ${tokenInfo.driverName}' : null;
str += '}';
}
str += '}';
return str;
}
