An action bar letting you switch between multiple views contained in a [class@ViewStack], via an [class@ViewSwitcher]. It is designed to be put at the bottom of a window and to be revealed only on really narrow windows, e.g. on mobile phones. It can't be revealed if there are less than two pages.

`AdwViewSwitcherBar` is intended to be used together with `AdwViewSwitcher` in a header bar, and a [class@Breakpoint] showing the view switcher bar on narrow sizes, while removing the view switcher from the header bar, as follows:

```xml <object class="AdwWindow"> <property name="width-request">360</property> <property name="height-request">200 </property> <child> <object class="AdwBreakpoint"> <condition>max-width: 550sp</condition> <setter object="switcher_bar" property="reveal">True</setter> <setter object="header_bar" property="title-widget"/> </object> </child> <property name="content"> <object class="AdwToolbarView"> <child type="top"> <object class="AdwHeaderBar" id="header_bar"> <property name="title-widget"> <object class="AdwViewSwitcher"> <property name="stack">stack</property> <property name="policy">wide</property> </object> </property> </object> </child> <property name="content"> <object class="AdwViewStack" id="stack"/> </property> <child type="bottom" > <object class="AdwViewSwitcherBar" id="switcher_bar"> <property name="stack">stack</property> </object> < /child> </object> </property> </object> ```

It's recommended to set [property@ViewSwitcher:policy] to `ADW_VIEW_SWITCHER_POLICY_WIDE` in this case.

You may have to adjust the breakpoint condition for your specific pages.
