UmengAnalyticsObserver class

A NavigatorObserver that sends events to Umeng Analytics when the currently active PageRoute changes.

When a route is pushed or popped, nameExtractor is used to extract a name from RouteSettings of the now active route and that name is sent to Umeng.

The following operations will result in sending a screen view event:

Navigator.pushNamed(context, '/contact/123');

Navigator.push<void>(context, MaterialPageRoute(
  settings: RouteSettings(name: '/contact/123'),
  builder: (_) => ContactDetail(123)));

Navigator.pushReplacement<void>(context, MaterialPageRoute(
  settings: RouteSettings(name: '/contact/123'),
  builder: (_) => ContactDetail(123)));

Navigator.pop(context);

To use it, add it to the navigatorObservers of your Navigator, e.g. if you're using a MaterialApp:

MaterialApp(
  home: MyAppHome(),
  navigatorObservers: [
    UmengAnalyticsObserver(),
  ],
);

You can also track screen views within your PageRoute by implementing PageRouteAware and subscribing it to UmengAnalyticsObserver. See the PageRouteObserver docs for an example.
