golden_screenshot

Utilities to automate screenshot generation using Flutter's golden tests.

Currently, there isn't much customization available, but I'll probably add more in the future.

The generated screenshots are suitable for the App Store, Play Store, F-Droid, Flathub (Linux), etc, and are saved in a Fastlane-compatible directory structure (e.g. metadata/en-US/images/phoneScreenshots/1_home.png). See lib/src/screenshot_device.dart for the list of devices and the paths where the screenshots are saved.

Getting started

In your pubspec.yaml file, add golden_screenshot as a dev_dependency before running flutter pub get:

dev_dependencies:
  flutter_test:
    sdk: flutter
  
  golden_screenshot: ^x.y.z # Replace x.y.z with the latest version

Then create a file in your test directory (e.g. test/screenshot_test.dart) and use example/test/screenshots_test.dart as a template to create your own tests.

The main portion might look something like this:

    _testGame(
      goldenFileName: '1_home',
      child: const HomePage(),
    );
    _testGame(
      gameSave: inProgressGameSave,
      frameColors: playPageFrameColors,
      goldenFileName: '2_play',
      child: const PlayPage(),
    );
    _testGame(
      goldenFileName: '4_shop',
      child: const ShopPage(),
    );
    _testGame(
      goldenFileName: '5_tutorial',
      child: const TutorialPage(),
    );
    _testGame(
      goldenFileName: '6_settings',
      child: const SettingsPage(),
    );

Usage

Once you have created your test file, run the following command to generate the screenshots:

flutter test test/screenshot_test.dart --update-goldens
