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() {
StringBuffer sb = StringBuffer();
for (MapEntry e in entries) {
sb.write(e.key.toString());
sb.write('=');
sb.write(e.value);
sb.write('\n');
}
return sb.toString();
}
