Subject: [PATCH] Update 'attributes' list type to enable nulls in header style
 dropdown config. (#1631)

In `select_header_style_dropdown_button_configurations.dart`, the 'attributes' list type has been modified. Now it accepts 'Attribute<int?>' instead of 'Attribute<int>'. This change allows for custom dropdown attributes with a nullable level.
