PopupMenuThemeData class Null safety
Defines the visual properties of the routes used to display popup menus as well as PopupMenuItem and PopupMenuDivider widgets.
Descendant widgets obtain the current PopupMenuThemeData object
using PopupMenuTheme.of(context)
. Instances of
PopupMenuThemeData can be customized with
PopupMenuThemeData.copyWith.
Typically, a PopupMenuThemeData is specified as part of the overall Theme with ThemeData.popupMenuTheme. Otherwise, PopupMenuTheme can be used to configure its own widget subtree.
All PopupMenuThemeData properties are null
by default.
If any of these properties are null, the popup menu will provide its
own defaults.
