flutter-floating-bottom-bar

Integrate, replace, or migrate to the `flutter_floating_bottom_bar` Flutter package — a floating widget host that sits above scrollable content and reacts to scroll events. Use this skill whenever the user mentions floating bottom bars, hide-on-scroll bars, replacing `BottomNavigationBar` / `NavigationBar` / `BottomAppBar`, swapping out third-party nav-bar packages (salomon, google_nav_bar, convex, persistent_bottom_nav_bar), migrating from `flutter_floating_bottom_bar` v1.x → v2.x, or fixing glitches with the package (jumpy springs, content clipped behind the bar, NestedScrollView not triggering hide, custom transition overshoot, FAB notch issues, double-attached controllers). Trigger even when the user does not say "flutter_floating_bottom_bar" by name — phrases like "I want a floating tab bar", "make my bottom bar hide on scroll", "iOS-style spring bottom navigation", or pasting a `BottomNavigationBar` and asking to "make it nicer" all qualify.
