masters property
The slide masters in the presentation.
A slide master contains all common page elements and the common properties for a set of layouts. They serve three purposes: - Placeholder shapes on a master contain the default text styles and shape properties of all placeholder shapes on pages that use that master. - The master page properties define the common page properties inherited by its layouts. - Any other shapes on the master slide appear on all slides using that master, regardless of their layout.
Implementation
core.List<Page>? masters;
