-# 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.

-# The following defines the version and build number for your application.
-# A version number is three numbers separated by dots, like 1.2.43
-# followed by an optional build number separated by a +.
-# Both the version and the builder number may be overridden in flutter
-# build by specifying --build-name and --build-number, respectively.
-# Read more about versioning at semver.org.
-#
-# This version is used _only_ for the Runner app, which is used if you just do
-# a `flutter run` or a `flutter make-host-app-editable`. It has no impact
-# on any other native host app that you embed your Flutter project into.
