MessageInputContext

MessageInputContext is provided by Channel. If you are not familiar with the React Context API, see the React docs.

Best Practices

• Prefer useMessageInputContext for consistent access and typings.
• Use context handlers (sendMessage, editMessage) to keep behavior aligned with the SDK.
• Keep input-related props stable to avoid re-renders while typing.
• Use openAttachmentPicker and closeAttachmentPicker helpers to keep picker state consistent.
• Respect cooldowns and permissions before allowing sends or uploads.

Basic Usage

Consume MessageInputContext in any child of Channel:

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

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

Alternatively, use the useMessageInputContext hook.

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

const { sendMessage, openAttachmentPicker } = useMessageInputContext();
