maybeMap<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeMap<TResult extends Object?>({
  1. TResult messageView(
    1. UConvoGetMessagesMessagesMessageView value
    )?,
  2. TResult deletedMessageView(
    1. UConvoGetMessagesMessagesDeletedMessageView value
    )?,
  3. TResult unknown(
    1. UConvoGetMessagesMessagesUnknown value
    )?,
  4. 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( UConvoGetMessagesMessagesMessageView value)?  messageView,TResult Function( UConvoGetMessagesMessagesDeletedMessageView value)?  deletedMessageView,TResult Function( UConvoGetMessagesMessagesUnknown value)?  unknown,required TResult orElse(),}){
final _that = this;
switch (_that) {
case UConvoGetMessagesMessagesMessageView() when messageView != null:
return messageView(_that);case UConvoGetMessagesMessagesDeletedMessageView() when deletedMessageView != null:
return deletedMessageView(_that);case UConvoGetMessagesMessagesUnknown() when unknown != null:
return unknown(_that);case _:
  return orElse();
