import { useContext } from "react";
import { ChannelsContext } from "stream-chat-react-native";
const { channels, reloadList } = useContext(ChannelsContext);ChannelsContext
ChannelsContext is provided by ChannelList. If you are not familiar with the React Context API, see the React docs.
Best Practices
- Use
useChannelsContextfor consistent access and typings. - Treat
channelsas read-only; use context helpers to mutate list state. - Use
reloadListwhen filters change, andrefreshListfor pull-to-refresh. - Check
hasNextPageandloadingNextPagebefore triggering pagination. - Keep list UI components lightweight to preserve scroll performance.
Basic Usage
Consume ChannelsContext in any child of ChannelList:
Alternatively, use the useChannelsContext hook.
import { useChannelsContext } from "stream-chat-react-native";
const { channels, reloadList } = useChannelsContext();Values
| Value | Description | Type |
|---|---|---|
additionalFlatListProps | Additional props provided to the underlying FlatList. Don't use additionalFlatListProps to access the FlatList ref, use setFlatListRef instead. | object |
channels | Array of channels currently loaded within the ChannelList component. | array |
channelListInitialized | A control prop used to determine whether the first query of the channel list has succeeded. Don't set this prop manually, it is set automatically by the ChannelList component. | boolean |
error | True if a call to query channels API call within ChannelList component results in error, either during first load or during pagination. | Error object | boolean |
hasNextPage | False if ChannelList has loaded all channels for the current filters. | boolean |
loadingChannels | True if ChannelList component is loading the first page of channels. | boolean |
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. Defaults to 0.1. | number |
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. | boolean |
loadNextPage | Loads the next page for ChannelList. | function |
maxUnreadCount | Max number to display within unread notification badge. The value cannot be higher than 255, which is the limit on backend side. Defaults to 255. | number |
mutedStatusPosition | Position of the muted status component within the Preview. Defaults to 'inlineTitle'. | trailingBottom | inlineTitle |
swipeActionsEnabled | If true, the user can swipe to perform actions on a channel. Defaults to true. | boolean |
numberOfSkeletons | The number of Skeleton items to display in the LoadingIndicator. Defaults to 6. | number |
onSelect | Function called when a user presses an item in the ChannelList. The function is called with the Channel instance corresponding to the list item as the only parameter. This callback is often used for navigating to a channel screen. Note: a Channel instance is not serializable and will therefore raise warnings if passed as a parameter through navigation to another screen. | function |
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. | boolean |
refreshList | Function to manually re-sync or refresh the channels in ChannelList component. Calling refreshList will trigger a RefreshControl on underlying FlatList component. | function |
reloadList | Manually reloads channels in ChannelList. Calling reloadList clears the current list and shows a loading indicator until new results arrive. | function |
setFlatListRef | Callback function to access the underlying FlatList ref. | function |

const flatListProps = { bounces: true };
<ChannelList additionalFlatListProps={flatListProps} />;onSelect
onSelect={(channel) => { /** navigation logic */ }}setFlatListRef
const flatListRef = useRef();
<ChannelList setFlatListRef={(ref) => (flatListRef.current = ref)} />;
