/**
 * AdwExpanderRow:
 *
 * A [class@Gtk.ListBoxRow] used to reveal widgets.
 *

 *   <source srcset="expander-row-dark.png" media="(prefers-color-scheme: dark)">
 *   <img src="expander-row.png" alt="expander-row">
 * </picture>
 *
 * The `AdwExpanderRow` widget allows the user to reveal or hide widgets below
 * it. It also allows the user to enable the expansion of the row, allowing to
 * disable all that the row contains.
 *
 * ## AdwExpanderRow as GtkBuildable
 *
 * The `AdwExpanderRow` implementation of the [iface@Gtk.Buildable] interface
 * supports adding a child as an suffix widget by specifying “suffix” as the
 * “type” attribute of a <child> element.
 *
 * It also supports adding it as a prefix widget by specifying “prefix” as the
 * “type” attribute of a <child> element.
 *
 * ## CSS nodes
 *
 * `AdwExpanderRow` has a main CSS node with name `row` and the `.expander`
 * style class. It has the `.empty` style class when it contains no children.
 *
 * It contains the subnodes `row.header` for its main embedded row,
 * `list.nested` for the list it can expand, and `image.expander-row-arrow` for
 * its arrow.
