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() {
final out = StringBuffer();
for (var i = 0; i < lines.length; i++) {
out.write(lines[i].toString());
if (i < lines.length - 1) out.write('\n');
}
return out.toString();
}
