emptyViewSubtitleVariants property
An optional array of subtitle variants for the template’s empty view. Provide the strings as localized displayable content and order from most- to least- preferred. When there are no items in the list, the template displays an empty view with a title and a subtitle in place of the items. If you update the list and provide items, the template automatically removes the empty view.
Implementation
final List<String>? emptyViewSubtitleVariants;
