SteamServerBrowser

An Android Flutter remake of SteamServerBrowser, focused on Steam server discovery and A2S query compatibility.

The project currently targets Android arm64-v8a.

Features

• Steam master server browsing through the Steam Web API
• Live A2S_INFO, A2S_PLAYER, and A2S_RULES queries
• Custom App ID input with automatic game-name lookup
• Favorites and manual IP:port server entries
• Map, tag, ping, player-count, country, and result-limit filters
• Offline GeoIP filtering with a user-imported .mmdb database
• Embedded Cronet HTTP client without a Google Play Services dependency
• System-language UI with all languages supported by Flutter Material

Requirements

• Flutter SDK
• Android SDK and command-line tools
• JDK 17
• Android device or emulator

Run

flutter pub get
flutter run

Build

flutter build apk --release --target-platform android-arm64

Only arm64-v8a native libraries are included in the APK. Release builds use the debug signing configuration by default, so configure a release signing key before publishing an APK.

Steam Web API

Master-list scans require a 32-character Steam Web API key. The Settings screen links to:

GeoIP

Country filtering is enabled after importing a compatible .mmdb database. ipinfo Lite is a suitable source.

Localization

The UI follows the Android system language and does not include an in-app language switch. Unsupported locales fall back to English.

Translation sources are stored in lib/l10n/app_*.arb. The project covers all 82 language codes supported by Flutter Material.

The product title Steam Server Browser remains unchanged in every language.

Regenerate localization classes after editing ARB files:

flutter gen-l10n

Project Layout

• lib/src/app.dart: UI and system-locale resolution
• lib/src/controller/server_browser_controller.dart: state and orchestration
• lib/src/network/steam_queries.dart: Steam Web API and A2S queries
• lib/src/geo/geo_ip_service.dart: MMDB import and lookup
• lib/src/persistence/preferences_service.dart: settings and favorites
• lib/l10n/: translation resources and generated classes
• test/: unit and localization tests

Notes

• Scan fetches a new master list and queries its servers.
• Refresh updates only the currently loaded server entries.
• Browse and Favorites use explicit buttons instead of pull-to-refresh.
• The result limit is capped at 10000.
