autoHideOnModal property
When true (default), destroys the native segmented control's PlatformView
while a modal sheet is presented above this widget's host route. Fixes
the iOS hybrid-composition z-order bleed (Issue #53). Requires
CNTabBarRouteObserver() to be registered in the app's
navigatorObservers. No effect on iOS < 26 / non-iOS (Flutter fallback).
Implementation
final bool autoHideOnModal;
