map<TResult extends Object?> method

@optionalTypeArgs TResult map<TResult extends Object?>({ required TResult messageView(UMessageViewReplyToMessageView value), required TResult deletedMessageView(UMessageViewReplyToDeletedMessageView value), required TResult messageBeforeUserJoinedGroupView(UMessageViewReplyToMessageBeforeUserJoinedGroupView value), required TResult unknown(UMessageViewReplyToUnknown value), })

A switch-like method, using callbacks.

Callbacks receives the raw object, upcasted. It is equivalent to doing:

switch (sealedClass) {
  case final Subclass value:
    return ...;
  case final Subclass2 value:
    return ...;
}

Implementation

@optionalTypeArgs TResult map<TResult extends Object?>({required TResult Function( UMessageViewReplyToMessageView value)  messageView,required TResult Function( UMessageViewReplyToDeletedMessageView value)  deletedMessageView,required TResult Function( UMessageViewReplyToMessageBeforeUserJoinedGroupView value)  messageBeforeUserJoinedGroupView,required TResult Function( UMessageViewReplyToUnknown value)  unknown,}){
final _that = this;
switch (_that) {
case UMessageViewReplyToMessageView():
return messageView(_that);case UMessageViewReplyToDeletedMessageView():
return deletedMessageView(_that);case UMessageViewReplyToMessageBeforeUserJoinedGroupView():
return messageBeforeUserJoinedGroupView(_that);case UMessageViewReplyToUnknown():
return unknown(_that);}
}
