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() {
int nf = _faces == null ? 0 : _faces!.length;
List<String> lst = ["Faces:${nf}"];
for (String c in _attributes.keys) {
lst.add("${c}:${_attributes[c]!.length}");
}
return "MESH[${name}] " + lst.join(" ");
}
