A list of Controls to display in a row after the title control.

Typically these controls are IconButtons representing common operations. For less common operations, consider using a PopupMenuButton as the last action.

automatically_imply_leading​

Controls whether we should try to imply the leading widget if null.

If True and leading is null, automatically try to deduce what the leading widget should be. If False and leading is null, leading space is given to title. If leading widget is not null, this parameter has no effect.
