CNTransitionObserver class

A navigation observer that automatically notifies native Cupertino components when route transitions begin and end.

This prevents visual artifacts with Liquid Glass effects during Flutter navigation transitions.

Usage

Add this observer to your app's navigatorObservers:

MaterialApp(
  navigatorObservers: [
    CNTransitionObserver(),
  ],
  // ...
)

Or with GoRouter:

GoRouter(
  observers: [
    CNTransitionObserver(),
  ],
  // ...
)
