One minor concern is that we currently can't trigger a re-render when the value from DeviceCapabilities.canUseTouchScreen() changes. This means we're dependent on external factors to trigger a re-render of AttachmentCarousel before it acknowledges any change in the canUseTouchScreen() value.

However, given the context of this specific use-case, this behavior seems acceptable.


const {attachments, initialPage, initialActiveSource, initialItem} = useMemo(() => extractAttachmentsFromReport(report, reportActions, source), [report, reportActions, source]);
