maybeMap<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeMap<TResult extends Object?>({
  1. TResult knownValue(
    1. LabelValueDefinitionSeverityKnownValue value
    )?,
  2. TResult unknown(
    1. LabelValueDefinitionSeverityUnknown value
    )?,
  3. required TResult orElse(),
})

A variant of map that fallback to returning orElse.

It is equivalent to doing:

switch (sealedClass) {
  case final Subclass value:
    return ...;
  case _:
    return orElse();
}

Implementation

@optionalTypeArgs TResult maybeMap<TResult extends Object?>({TResult Function( LabelValueDefinitionSeverityKnownValue value)?  knownValue,TResult Function( LabelValueDefinitionSeverityUnknown value)?  unknown,required TResult orElse(),}){
final _that = this;
switch (_that) {
case LabelValueDefinitionSeverityKnownValue() when knownValue != null:
return knownValue(_that);case LabelValueDefinitionSeverityUnknown() when unknown != null:
return unknown(_that);case _:
  return orElse();

}
