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 safeString = Error.safeToString(unsupportedObject);
final prefix = cause != null
? 'Converting object to an encodable object failed:'
: 'Converting object did not return an encodable object:';
return '$prefix $safeString';
}
