MessageInputContext

MessageInputContext is provided by Channel component. If you are not familiar with React Context API, please read about it on React docs.

Basic Usage

MessageInputContext can be consumed by any of the child component of Channel component as following:

import { useContext } from 'react';
import { MessageInputContext } from 'stream-chat-react-native';

const { sendMessage, toggleAttachmentPicker } = useContext(MessageInputContext);

Alternatively, you can also use useMessageInputContext hook provided by library to consume MessageInputContext.

import { useMessageInputContext } from 'stream-chat-react-native';

const { sendMessage, toggleAttachmentPicker } = useMessageInputContext();
