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 sb = StringBuffer();
if (path.isNotEmpty) {
sb
..write(path.join(' '))
..write(' ');
}
for (final entry in values.entries) {
sb.write('${entry.key}: ${entry.value} ');
}
for (final entry in abbrs.entries) {
sb.write('${entry.key}: ${entry.value} ');
}
if (rest.isNotEmpty) {
sb.write('rest: ${rest.join(' ')}');
}
return 'Args(${sb.toString().trim()})';
}
