WidgetTracker class

A class used for manually tracking activities throughout the app.

The available methods permit specifying the start and end of a Flutter widget to be reflected as an app screen in the controller.

Warning: Be sure to be using unique widget names. Duplicate names might result in unexpected behavior.

For apps using named routes, see NavigationObserver.
