map<TResult extends Object?> method

  1. @optionalTypeArgs
TResult map<TResult extends Object?>({
  1. required TResult messageView(
    1. UConvoViewLastMessageMessageView value
    ),
  2. required TResult deletedMessageView(
    1. UConvoViewLastMessageDeletedMessageView value
    ),
  3. required TResult unknown(
    1. UConvoViewLastMessageUnknown 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( UConvoViewLastMessageMessageView value)  messageView,required TResult Function( UConvoViewLastMessageDeletedMessageView value)  deletedMessageView,required TResult Function( UConvoViewLastMessageUnknown value)  unknown,}){
final _that = this;
switch (_that) {
case UConvoViewLastMessageMessageView():
return messageView(_that);case UConvoViewLastMessageDeletedMessageView():
return deletedMessageView(_that);case UConvoViewLastMessageUnknown():
return unknown(_that);}
}
