+# iOS Add2App Life Cycle Test
+
+This application demonstrates some basic functionality for Add2App,
+along with a native iOS ViewController as a baseline and to demonstrate
+interaction.
+
+The following functionality is currently implemented:
+
+1. A regular iOS view controller (UIViewController), similar to the default
+   `flutter create` template (NativeViewController.m).
+1. A FlutterViewController subclass that takes over full screen. Demos showing
+   this both from a cold/fresh engine state and a warm engine state
+   (FullScreenViewController.m).
+1. A demo of pushing a FlutterViewController on as a child view.
+1. A demo of showing both the native and the Flutter views using a platform
+   channel to to interact with each other (HybridViewController.m).
+1. A demo of showing two FlutterViewControllers simultaneously
+   (DualViewController.m).
+
+A few key things are tested here (IntegrationTests.m):
+
+1. The ability to pre-warm the engine and attach/detatch a ViewController from
+   it.
+1. The ability to use platform channels to communicate between views.
+1. The ability to simultaneously run two instances of the engine.
+1. That a FlutterViewController can be freed when no longer in use (also tested
+   from FlutterViewControllerTests.m).
+1. That a FlutterEngine can be freed when no longer in use.
