SteamServerBrowser for Android is a Flutter port focused on Steam server discovery and A2S-compatible server queries. Features: * Browse Steam master server results through the Steam Web API. * Query live A2S_INFO, A2S_PLAYER, and A2S_RULES data. * Refresh loaded servers without fetching a new master list. * Save favorites and manually add IP:port entries. * Filter by map, tags, ping, players, countries, and local search text. * Import an optional MMDB database for offline country lookup. The app does not bundle an MMDB database. Geo features stay disabled until the user imports one manually.
