leading property

Widget? leading

A widget to display before the title.

If this is null and automaticallyImplyLeading is set to true, the NewGradientAppBar will imply an appropriate widget. For example, if the NewGradientAppBar is in a Scaffold that also has a Drawer, the Scaffold will fill this widget with an IconButton that opens the drawer. If there's no Drawer and the parent Navigator can go back, the NewGradientAppBar will use a BackButton that calls Navigator.maybePop.

Implementation

final Widget? leading;
