LiquidNavigatorObserver class

A NavigatorObserver that emits a screen event on every route change, giving you automatic screen tracking with no per-screen instrumentation.

MaterialApp(
  navigatorObservers: [LiquidNavigatorObserver(liquid)],
);

By default the route's RouteSettings.name is used as the screen name; routes without a name are skipped. Supply nameExtractor to customize.
