Flutter Cross-Platform Implementation of bitchat

[ebwood]

Hi! Claude Opus 4.6 (AI) wrote a Flutter cross-platform implementation of bitchat, with full protocol compatibility (BLE UUIDs, Nostr relay URLs, Noise Protocol, binary packet format — all matching the original iOS/Android versions).

It covers iOS, Android, and macOS from a single Dart codebase, with 89 files, ~15K lines of code, and 316 unit tests.

This is a learning/reference project — not intended for App Store release. Just wanted to share in case it's useful to the community. Thanks for building bitchat! 🙏
