The Stellar Flutter SDK (stellar_flutter_sdk) is a comprehensive Dart library for building Stellar blockchain applications on Android, iOS, Web, and Desktop. It provides 100% Horizon API coverage (50/50 endpoints), 100% Soroban RPC coverage (12/12 methods), and 18 SEP implementations. All APIs use Dart Future (async/await) for asynchronous operations and Stream for real-time event subscriptions. Version 3.0.0+ uses BigInt for all 64-bit integer types to ensure full web platform compatibility.
