when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. ChatCompletionListObject object,
    2. List<CreateChatCompletionResponse> data,
    3. String? firstId,
    4. String? lastId,
    5. bool hasMore,
    )
)

A switch-like method, using callbacks.

As opposed to map, this offers destructuring. It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case Subclass2(:final field2):
    return ...;
}

Implementation

@optionalTypeArgs TResult when<TResult extends Object?>(TResult Function( ChatCompletionListObject object,  List<CreateChatCompletionResponse> data, @JsonKey(name: 'first_id', includeIfNull: false)  String? firstId, @JsonKey(name: 'last_id', includeIfNull: false)  String? lastId, @JsonKey(name: 'has_more')  bool hasMore)  $default,) {final _that = this;
switch (_that) {
case _ChatCompletionList():
return $default(_that.object,_that.data,_that.firstId,_that.lastId,_that.hasMore);case _:
  throw StateError('Unexpected subclass');

}
}
