List<Widget>? persistentFooterButtons

A set of buttons that are displayed at the bottom of the scaffold.

Typically this is a list of TextButton widgets. These buttons are persistently visible, even if the body of the scaffold scrolls.

These widgets will be wrapped in a ButtonBar.

The persistentFooterButtons are rendered above the bottomNavigationBar but below the body.
