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 'RGBController ==> name: $name, vendor: $vendor, description: $description, version: $version, serial: $serial, location: $location, modes: $modes, zones: $zones, leds: $leds, colors: $colors';
}
