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() {
return 'PhoneNumber { '
'countryCode: $countryCode, '
'e164: $e164, '
'national: $national, '
'type: $type, '
'international: $international, '
'nationalNumber: $nationalNumber '
'}';
}
