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() {
String m = "";
for (final i in toJson().entries) {
final ln = List<int>.from(i.value["h"]);
final sm = ln.fold<int>(0, (c, p) => c + p);
m += "${i.key}:${i.value["h"]} sum: $sm \n";
}
return m;
}
