MessageList

MessageList component uses FlatList to render list of messages within a channel (provided as a prop to parent Channel component). This component must be rendered within Channel component. It uses message.type property, to render corresponding view for message.

General Usage

import {
  Chat,
  Channel,
  OverlayProvider,
  MessageList,
} from "stream-chat-react-native";

const App = () => {
  return (
    <OverlayProvider>
      <Chat client={client}>
        <Channel channel={channel}>
          <MessageList />
        </Channel>
      </Chat>
    </OverlayProvider>
  );
};

Props

additionalFlatListProps

Set any additional props on underlying FlatList.

const flatListProps = { bounces: true };

<MessageList additionalFlatListProps={flatListProps} />;

inverted

Sets the inverted prop on underlying FlatList.

isListActive

noGroupByUser

When true, consecutive messages from same user won’t be grouped together. Avatar for user of message is only shown for last message of the group.

onListScroll

The event has the following shape (all values are numbers):

{
  nativeEvent: {
    contentInset: {bottom, left, right, top},
    contentOffset: {x, y},
    contentSize: {height, width},
    layoutMeasurement: {height, width},
    zoomScale
  }
}

onThreadSelect

setFlatListRef

Use this callback function to gain access to the underlying FlatList ref.

Example

<MessageList setFlatListRef={(ref) => (flRef.current = ref)} />;

threadList

Boolean whether or not the Messages in the MessageList are part of a Thread.
