maybeMap<TResult extends Object?> method

@optionalTypeArgs TResult maybeMap<TResult extends Object?>({ TResult richtextFacetMention(URichtextFacetFeaturesRichtextFacetMention value)?, TResult richtextFacetLink(URichtextFacetFeaturesRichtextFacetLink value)?, TResult richtextFacetTag(URichtextFacetFeaturesRichtextFacetTag value)?, TResult unknown(URichtextFacetFeaturesUnknown value)?, 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( URichtextFacetFeaturesRichtextFacetMention value)?  richtextFacetMention,TResult Function( URichtextFacetFeaturesRichtextFacetLink value)?  richtextFacetLink,TResult Function( URichtextFacetFeaturesRichtextFacetTag value)?  richtextFacetTag,TResult Function( URichtextFacetFeaturesUnknown value)?  unknown,required TResult orElse(),}){
final _that = this;
switch (_that) {
case URichtextFacetFeaturesRichtextFacetMention() when richtextFacetMention != null:
return richtextFacetMention(_that);case URichtextFacetFeaturesRichtextFacetLink() when richtextFacetLink != null:
return richtextFacetLink(_that);case URichtextFacetFeaturesRichtextFacetTag() when richtextFacetTag != null:
return richtextFacetTag(_that);case URichtextFacetFeaturesUnknown() when unknown != null:
return unknown(_that);case _:
  return orElse();
