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 infos = Map<String, dynamic>.fromEntries(
details?.entries.where((element) => element.value != null) ?? []);
if (infos.isEmpty) return "$runtimeType($message)";
final String msg =
"$message ${infos.entries.map((e) => "${e.key}: ${e.value}").join(", ")}";
return "$runtimeType($msg)";
}
