Source url: https://docs.flutter.dev/learn/pathway/tutorial/slivers **Page**: Flutter Docs **Tutorial Scope**: Flutter UI 102 **Global Lesson number**: 15 - _Advanced scrolling and slivers_ **Lesson Section**: 07 - _Use `SliverList` for alphabetized sections_ **Problem Description** In Lesson 15, Section 4, Code Snippet 2 [`lib/screens/contacts.dart`], the `automaticallyImplyLeading` default, named parameter is introduced in the `_ContactListView` constructor, but it is unused. In the subsequent Section (5: _Add search integration with slivers_), Code Snippet 1, the `automaticallyImplyLeading` parameter is omitted from the `_ContactListView` class. However, by Section 7, the `automaticallyImplyLeading` parameter is referenced in the `_ContactListView` build method, but it throws an undefined name error due to intermittent omission of the `automaticallyImplyLeading` parameter: `CupertinoSliverNavigationBar.search( largeTitle: Text(contactList.title), automaticallyImplyLeading: automaticallyImplyLeading, ...` To fix this, the `automaticallyImplyLeading` default parameter is reintroduced to the `_ContactListView` class as it originally was in Section 4.

Code Review
This pull request correctly addresses an omission in the 'Advanced scrolling and slivers' tutorial. By reintroducing the automaticallyImplyLeading parameter to the _ContactListView widget, it resolves a potential undefined name error that would occur in a later section of the tutorial. My review includes a minor suggestion to remove an extra blank line to maintain code style consistency.

This change introduces an extra blank line. According to the Dart style guide, there should be only one blank line between class members like fields and methods. Please remove this extra line to maintain code style consistency.

Definitely. I will correct this to adhere to the style guide.
