unified_game_services_google_play 0.1.0

Auto-selecting Google Play Games provider for unified_game_services — native Play Games SDK on Android, REST elsewhere. Pure Dart, no Flutter.

example/unified_game_services_google_play_example.dart

// Auto-selecting Google Play Games demo.
//
// `GooglePlayGames.create` picks the right provider for the platform it runs
// on: native Play Games v2 SDK on Android, REST everywhere else (desktop,
// CLI, server, web). This CLI can only exercise the REST side (there's no
// Android `Activity` to hand it outside an app), so it runs the loopback
// OAuth flow and treats `auth` as the only required input — on Android you'd
// instead pass `activityResolver` (see
// `unified_game_services_google_play_flutter` for a Flutter host that wires
// that for you automatically).
//
// Prerequisites:
//   * A Google Cloud OAuth client of type "Desktop app" → its client id.
//   * A Play Console game with the Games API enabled and your account added
//     as a tester (while the game is unpublished).
//
// Usage:
//   dart run example/unified_game_services_google_play_example.dart \
//     --client-id <DESKTOP_CLIENT_ID> \
//     [--achievement <unified_id> --achievement-native <CgkI...>]
