leading property

Widget? leading

The widget at the beggining of the app bar, before title.

Typically the leading widget is an Icon or an IconButton.

If this is null and automaticallyImplyLeading is set to true, the view will imply an appropriate widget. If the parent Navigator can go back, the app bar will use an IconButton that calls Navigator.maybePop.

See also:

• automaticallyImplyLeading, that controls whether we should try to imply the leading widget, if leading is null

Implementation

final Widget? leading;
