This is documentation for Stream Chat React-native SDK v3, which is no longer actively maintained. For up-to-date documentation, see the latest version (v5).

Gallery

Component to render image attachments within the MessageList.

Basic Usage

You can customize the Gallery component and provide it back to the SDK via the Gallery prop on Channel if desired.

import { Channel, Gallery } from 'stream-chat-react-native';

<Channel Gallery={() => <Gallery preventPress />}

Props

additionalTouchableProps

Additional props provided to the underlying TouchableOpacity used by components within a message such as MessageContent.

Type

alignment

Sets if the message should be aligned to right or left side of list.

Type	Default
enum(‘right’, ‘left’)	‘right’

`groupStyles`

Position of message in the group. A message group is a group of consecutive messages from the same user. groupStyles can be used to style the message as per their position in message group.

for example user avatar (to which message belongs to) is only showed for last (bottom) message in group.

Type
array of enum(‘top’, ‘bottom’, ‘middle’, ‘single’)

hasThreadReplies

Weather current message has any thread replies or not. This boolean is used for setting borderBottomLeftRadius for left aligned messages and borderBottomRightRadius for right aligned messages.

legacyImageViewerSwipeBehaviour

Note: This prop is available only in SDK version >= v3.9.0

Enables/disables the legacy image viewer behavior.

By default, when you open (press) an image attachment it opens the image in a full-screen image viewer. Within the viewer, you can keep swiping left to scroll through all the images that have been loaded within a channel so far. This creates quite a lot of extra work for the JS thread to keep track of image attachments loaded in a channel and pre-populating them in the viewer for smooth transitions.

For performance reason, you can switch to an alternate UX for the image viewer where image attachments are only loaded for the selected messages in a viewer, by setting this prop to false.

Type	Default
boolean	true

`messageId`

Type
string

`messageText`

Text content of current message - message.text. This prop gets used for styling purpose of gallery.
