dev/integration_tests/flutter_driver_screenshot_test/README.md

+# Summary
+
+This test contains an app with a main page and subpages.
+The main page contains a list of buttons; each button leads to a designated subpage when tapped on.
+Each subpage should display some simple UIs to the screenshot tested.
+
+The flutter driver test runs the app and opens each page to take a screenshot.
+
+Use `main_test.dart` to test against golden files stored on Flutter Gold.
+
+Note that new binaries can't be checked in the Flutter repo, so use [Flutter Gold](https://github.com/flutter/flutter/wiki/Writing-a-golden-file-test-for-package:flutter) instead.
+
+# Add a new page to test
+
+1. Create a new class that extends `Page` and implement the UI to be tested in the `build` method.
+2. The new class should set a static `title` and `key`
+3. Add an instance of the new class to the `_allPages` list in the `main.dart`
+4. Create a new test case similar to `"'A page with an image screenshot"` in `test_driver/main_test.dart` to run the screenshot test.
+
+An example of a `Page` subclass can be found in `lib/image_page.dart`
+
+# Environments
+
+* Device Lab which runs the app on iPhone 6s.
+* LUCI which runs the app on a Fuchsia NUC device.

+# Launch Screen Assets
+
+You can customize the launch screen with your own desired assets by replacing the image files in this directory.
+
+You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.
