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 'Subline{active: $active, code: $code, color: $color, id: $id, name: $name, type: $type, way: $way, stations: $stations, parentLine: $parentLine, towns: $towns, main: $main, distance: $distance}';
}
