maybeMap<TResult extends Object?> method

@optionalTypeArgs TResult maybeMap<TResult extends Object?>({ TResult directConvoMember(UProfileViewBasicKindDirectConvoMember value)?, TResult groupConvoMember(UProfileViewBasicKindGroupConvoMember value)?, TResult pastGroupConvoMember(UProfileViewBasicKindPastGroupConvoMember value)?, TResult unknown(UProfileViewBasicKindUnknown 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( UProfileViewBasicKindDirectConvoMember value)?  directConvoMember,TResult Function( UProfileViewBasicKindGroupConvoMember value)?  groupConvoMember,TResult Function( UProfileViewBasicKindPastGroupConvoMember value)?  pastGroupConvoMember,TResult Function( UProfileViewBasicKindUnknown value)?  unknown,required TResult orElse(),}){
final _that = this;
switch (_that) {
case UProfileViewBasicKindDirectConvoMember() when directConvoMember != null:
return directConvoMember(_that);case UProfileViewBasicKindGroupConvoMember() when groupConvoMember != null:
return groupConvoMember(_that);case UProfileViewBasicKindPastGroupConvoMember() when pastGroupConvoMember != null:
return pastGroupConvoMember(_that);case UProfileViewBasicKindUnknown() when unknown != null:
return unknown(_that);case _:
  return orElse();
