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 params = namedProps.entries
.map((e) =>
hasValue(e.value) ? '${e.key}:${_formatPrint(e.value)}' : null)
.where((o) => o != null)
.join(', ');
return '$runtimeType($params)';
}
