Broken link in NavigationRail documentation #175757
Description
Steps to reproduce
Go to https://api.flutter.dev/flutter/material/NavigationRail-class.html or packages/flutter/lib/src/material/navigation_rail.dart. See these lines:
/// Adaptive layouts can build different instances of the [Scaffold] in order to
/// have a navigation rail for more horizontal layouts and a bottom navigation
/// bar for more vertical layouts. See
/// [the adaptive_scaffold.dart sample](https://github.com/flutter/samples/blob/main/experimental/web_dashboard/lib/src/widgets/third_party/adaptive_scaffold.dart)
/// for an example.
Link leading to flutter/samples repository does not work, repository itself is deprecated
Expected results
No broken links in documentation. Probably these lines can be removed at all?
Actual results
