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 'UserException{' +
[
joinCauses(_msgOrCode(), reason)
.replaceAll(' ', ' ')
.replaceAll('\n', '|')
.replaceAll('||', '|'),
(ifOpenDialog ? null : 'ifOpenDialog: false'),
((errorText?.isNotEmpty ?? false) ? 'errorText: "$errorText"' : null),
].where((x) => x?.isNotEmpty ?? false).join(', ') +
'}';
}
