Added #

🚀 Core QUIC Support

• Client endpoints: Create QUIC client connections with createClientEndpoint()
• Server endpoints: Create QUIC server connections with createServerEndpoint()
• TLS configuration: Full support for TLS 1.3 with serverConfigWithSingleCert()
• Stream operations: Bidirectional and unidirectional streams for data transfer
• Connection management: Connection stats, RTT monitoring, and remote address info
• Datagram support: Unreliable message delivery for real-time applications

🎯 Convenience API

• HTTP-style interface: Familiar GET/POST methods with QUIC performance
• Connection pooling: Automatic connection reuse and management
• Retry logic: Built-in exponential backoff for failed requests
• Timeout protection: Configurable timeouts for all operations
• Configuration management: Fine-grained control over connection parameters

🔧 Developer Experience

• Async/await support: Full Flutter integration with Future-based APIs
• Memory safety: Rust ownership prevents memory leaks and corruption
• Type safety: Generated bindings with compile-time guarantees
• Error handling: Specific error types for different failure scenarios
• Cross-platform: Support for Android, iOS, Windows, macOS, and Linux

📊 Production Features

• Certificate loading: Support for PEM/DER certificates and private keys
• Connection migration: Seamless WiFi ↔ cellular network switching
• 0-RTT connections: Instant reconnection for repeat connections
• Stream multiplexing: Multiple independent streams over single connection
• Flow control: Built-in congestion control and bandwidth management

Technical Details #

API Coverage

• ✅ Core API: Complete 1:1 Quinn library mapping
• ✅ Convenience API: HTTP-style wrapper for common use cases

• Mobile-optimized: Battery-aware optimizations for mobile platforms

Known Limitations #

• Web platform: Not supported (WebTransport may be added in future)
• HTTP/3 semantics: Raw QUIC transport only (HTTP/3 helpers planned)
• Advanced TLS: Custom certificate validation not yet implemented

Dependencies #

• quinn = "0.11" - Core QUIC implementation
• flutter_rust_bridge = "2.11.1" - Rust-Flutter integration
• tokio - Async runtime for Rust operations
• rustls - TLS 1.3 implementation

Breaking Changes #

• None (initial release)

---

Note: This is a beta release intended for testing and development. While the API is stable and feature-complete, it is not recommended for production use until the stable 1.0.0 release.
