Constructors

StreamPollVoteListController({required Channel channel, required String pollId, StreamPollVoteEventHandler? eventHandler, Filter? filter, List<SortOption>? sort, int limit = defaultPollVotePagedLimit})
Creates a Stream poll vote list controller.
StreamPollVoteListController.fromValue(PagedValue<String, PollVote> value, {required Channel channel, required String pollId, StreamPollVoteEventHandler? eventHandler, Filter? filter, List<SortOption>? sort, int limit = defaultPollVotePagedLimit})
Creates a StreamPollVoteListController from the passed value.

Methods

addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited
appendLastPage(List<PollVote> newItems) → void
Appends newItems to the previously loaded ones and sets the next page key to null.
inherited
appendPage({required List<PollVote> newItems, required String nextPageKey}) → void
Appends newItems to the previously loaded ones and replaces the next page's key.
inherited
dispose() → void
Discards any resources used by the object. After this is called, the object is not in a usable state and should be discarded (calls to addListener will throw after the object is disposed).
override
doInitialLoad() → Future<void>
Load initial data from the server.
override
loadMore(String nextPageKey) → Future<void>
Load more data from the server using nextPageKey.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void
Call all the registered listeners.
inherited
pauseEventsSubscription([Future<void>? resumeSignal]) → void
Pauses all subscriptions added to this composite.
refresh({bool resetValue = true}) → Future<void>
Refresh the data presented by this PagedValueNotifier.
override
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
resumeEventsSubscription() → void
Resumes all subscriptions added to this composite.
retry() → Future<void>
Retry any failed load requests.
inherited
toString() → String
A string representation of this object.
