MessageInput

MessageInput provides UI and functionality for composing messages (attachment picker, commands, mentions, autocomplete). It must be rendered inside Channel.

Best Practices

• Render MessageInput inside Channel to ensure composer state is available.
• Customize via Channel props first to keep behavior consistent.
• Keep additionalTextInputProps stable to avoid re-renders.
• Respect cooldowns and permissions to prevent invalid sends.
• Use built-in components for attachments and audio before rolling your own.

General Usage

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

const client = StreamChat.getInstance("api_key");

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

TypeScript

File type

The File type is now exported from the stream-chat-react-native package and extends the FileReference type from the stream-chat package. It looks like this:

import { FileReference } from "stream-chat";

export type File = FileReference;

Props

attachmentPickerBottomSheetHeight

Height of the attachment picker bottom sheet when open.

attachmentSelectionBarHeight

Height of the attachment selection bar in the attachment picker.

bottomInset

Offsets the MessageList when the attachment picker opens. Use to override bottomInset from AttachmentPickerContext.

additionalTextInputProps

asyncMessagesLockDistance

Pixels the user must drag upward to lock recording and lift their finger without stopping it.

asyncMessagesMinimumPressDuration

Minimum press duration (ms) on the record button to start voice recording.

asyncMessagesMultiSendEnabled

When enabled, recordings don’t send immediately. They stack in the composer so users can send multiple voice recordings in one message.

asyncMessagesSlideToCancelDistance

Pixels the user must drag toward the leading side to cancel voice recording.

audioRecordingEnabled

Enable or disable audio recording.

channel

Channel instance from the Stream Chat client.

closeAttachmentPicker

Dismiss the attachment picker, if its already open.

closePollCreationDialog

Function called whenever the close button is pressed on the poll creation modal. Has no effect if PollCreateContent is custom.
