Phase 3 SDK expansion - Flutter/Dart implementations:
- Database SDK: Multi-model database with Key-Value, Document,
Vector, and Time Series stores
- Hosting SDK: Decentralized web hosting with domain management,
DNS, deployments, and SSL provisioning
- Bridge SDK: Cross-chain asset transfers with lock-mint and
burn-unlock patterns
All SDKs follow consistent patterns with:
- Async/await API using Futures
- Proper error handling with typed exceptions
- Configurable retry logic and timeouts
- Full type safety with Dart's type system
