showPanel top-level property

Facet<PanelConstructor?, List<PanelConstructor?>> showPanel
final

Opening a panel is done by providing a constructor function for the panel through this facet. (The panel is closed again when its constructor is no longer provided.) Values of null are ignored.

Implementation

final Facet<PanelConstructor?, List<PanelConstructor?>> showPanel =
    Facet.define();
