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() {
if (command != null) {
final name = command!.substring(1);
return fromColumn == null ? name : '$name$fromColumn-$toColumn';
}
final s = style == LineStyle.solid ? 'hline' : 'hdashline';
return fromColumn == null ? s : 'cline$fromColumn-$toColumn';
}
