+# Splash Demo: Kitchen Sink
+
+This project is an example of a splash screen that shows a logo for a launch screen and then
+zooms that logo towards the screen while fading content beneath it, masked by the logo.
+
+The purpose of this example project is to push the limits of what Flutter's splash system affords.
+
+This project is also run as a device lab test via Flutter Driver.
+
+The files that are relevant to test execution are:
+
+ - /test_driver/main.dart
+ - /test_driver/main_test.dart
+ - /android/app/src/main/java/io/flutter/splash_screen_kitchen_sink/MainActivity.java
+ 
+ The files that should be inspected to learn about splash behavior are:
+ 
+ - /android/app/src/main/java/io/flutter/splash_screen_kitchen_sink/FlutterZoomSplashScreen.java
+ - /android/app/src/main/java/io/flutter/splash_screen_kitchen_sink/FlutterZoomSplashView.java
+ 
+ Communication takes place from Android to Flutter to Driver to communicate splash screen events.
+ This communication takes place over a channel called "testChannel", whose definition can be
+ found in `MainActivity.java` and `test_driver/main.dart`.

+# Splash Demo: Never ending splash animation
+
+This project is an example of a splash screen that displays an animation indefinitely.
+
+A never ending animation is provided as a demo so that developers can manually verify that 
+orientation changes and other UI destruction processes do not cause issues with Flutter's splash 
+system for Android.

+# Splash Demo: Long transition animation
+
+This project is an example of a splash screen that fades very slowly to the Flutter UI.
+
+A slow transition is provided as a demo so that developers can manually verify that orientation 
+changes and other UI destruction processes do not cause issues with Flutter's splash system for
+Android.

+# A version number is three numbers separated by dots, like 1.2.43

+# Both the version and the builder number may be overridden in flutter
+# build by specifying --build-name and --build-number, respectively.
+# In Android, build-name is used as versionName while build-number used as versionCode.
+# Read more about Android versioning at https://developer.android.com/studio/publish/versioning
+# In iOS, build-name is used as CFBundleShortVersionString while build-number used as CFBundleVersion.
