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 s = StringBuffer();
for (final name in directories.keys) {
s.write('$name\n');
final directory = directories[name]!;
for (final tag in directory.keys) {
final value = directory[tag];
if (value == null) {
s.write('\t${getTagName(tag)}\n');
} else {
s.write('\t${getTagName(tag)}: $value\n');
}
}
for (final subName in directory.sub.keys) {
s.write('$subName\n');
final subDirectory = directory.sub[subName];
for (final tag in subDirectory.keys) {
final value = subDirectory[tag];
if (value == null) {
s.write('\t${getTagName(tag)}\n');
} else {
s.write('\t${getTagName(tag)}: $value\n');
}
}
}
}
return s.toString();
