actions property
Widgets to display in a row after the title widget.
Typically these widgets are IconButtons representing common operations. For less common operations, consider using a PopupMenuButton as the last action.
The actions become the trailing component of the NavigationToolBar
built
by this widget. The height of each action is constrained to be no bigger
than the toolbar's height, which is kToolbarHeight.
Implementation
final List<Widget>? actions;
