ULabelValueDefinitionSeverity class
Overview
This is an union object to improve safety and convenience of objects using Enum.
Enum provides a very powerful type for a specific group of data, but at the same time it means a loss of flexibility: values not defined in Enum are either completely ignored or an exception is thrown if parsing fails. This union object exists to solve that problem.
This union object handles the KnownValue
, a known enum value defined in Lexicon,
and the UnknownValue
, an unknown string value not defined in Lexicon. In other words,
it can handle unknown values while enjoying the type safety of Enum.
Usage
// use when syntax.
final value = object.when(
knownValue: (data) => data, // => KnownLabelValueDefinitionSeverity
unknownValue: (data) => data, // => String
);
// or simpler way.
if (object.isKnownValue) {
print(object.knownValue); // => KnownLabelValueDefinitionSeverity or null
} else if (object.isUnknownValue) {
print(object.unknownValue); // => String or null
}
