ChannelListMessenger

Renders the list of channels inside ChannelList. This is the default component for the List prop.

Best Practices

• Keep list item rendering lightweight to preserve scroll performance.
• Pass stable additionalFlatListProps and memoize callbacks.
• Use loadMoreThreshold conservatively to avoid excessive pagination calls.
• Show clear EmptyStateIndicator and LoadingErrorIndicator states.
• Avoid modifying channels directly; use context setters like reloadList or refreshList.

Props

additionalFlatListProps

Additional props provided to the underlying FlatList.

Example

const flatListProps = { bounces: true };

<ChannelList additionalFlatListProps={flatListProps} />;

channels

Array of channels currently loaded within the ChannelList component.

error

True if a call to query channels API call within ChannelList component results in error, either during first load or during pagination.

loadingChannels

True if ChannelList component is loading the first page of channels.

loadingNextPage

True if ChannelList component is loading more channels as part of pagination. This will be set to true when user scrolls to bottom of the list and hasNextPage is true.

loadMoreThreshold

Sets the onEndReachedThreshold of the underlying FlatList. We recommend using 0.1 as the default value for this prop, as changing it might hit additional channelQuery calls, and you might reach the limit.

loadNextPage

Loads the next page for ChannelList.

refreshing

True if ChannelList component is refreshing the list (using refreshList function call). Refreshing state will be triggered either when user executes pull-to-refresh gesture or if network connection is being recovered. This value is attached to refreshing prop of underlying FlatList component of ChannelList.

refreshList

Function to manually re-sync or refresh the channels in ChannelList component.

reloadList

Manually reloads channels in ChannelList.

setFlatListRef

Callback function to access the underlying FlatList ref.

Example

const flatListRef = useRef();

<ChannelList setFlatListRef={(ref) => (flatListRef.current = ref)} />;

UI Component Props

EmptyStateIndicator

Rendered when the channel list is empty and not loading via the ListEmptyComponent prop on the FlatList.

FooterLoadingIndicator

Rendered when loadingNextPage from ChannelsContext is true via the ListFooterComponent prop on the FlatList.

ListHeaderComponent

Rendered when provided if the channel list is not empty via the ListHeaderComponent prop on the FlatList.

LoadingErrorIndicator

Rendered when error from ChannelsContext is true, and the channel list is empty and not loading.

LoadingIndicator

Rendered when the channel list is empty and loading via the ListEmptyComponent prop on the FlatList.
