xmtp_plugin 1.0.3

A Flutter plugin for XMTP decentralized messaging. Supports DMs, group chats, content codecs, consent management, and real-time streaming across Android, iOS, Windows, and Web.

1.0.3

• Web: Upgraded to XMTP Browser SDK v6. Complete rewrite of the JavaScript bridge (web/xmtp_client_manager.js). All v6 API changes adopted: createDm/createGroup (renamed), sendText (replaces send), IdentifierKind enums, accountIdentifiers (replaces addresses), fetchInboxState/inboxState split, ConsentState/ConsentEntityType enums.
• Web: Switched to Vite bundler for proper Web Worker and WASM handling. Includes vite.config.js and build instructions.
• Web: Added viem for proper secp256k1 ECDSA message signing (replaces SHA-256 mock signer).
• Web: Fixed client.close() — previous versions leaked Web Workers on re-initialization, blocking OPFS database access for new clients.
• Web: Fixed InboxState field mapping — accountIdentifiers (not identifiers), recoveryIdentifier (not recoveryIdentity), IdentifierKind enum conversion.
• Web: Fixed listGroupMembers — updated from m.addresses (v5) to m.accountIdentifiers (v6).
• Cross-platform: Conditional export of XmtpPluginWindows using dart.library.js_interop guard. Web gets a no-op stub, native platforms get the real FFI implementation. Fixes dart2js compilation failure when building for web.
• Cross-platform: Defensive encodedContent type handling — List<dynamic> (from JS interop) is now converted to Uint8List in both _processMessages and subscribeToAllMessages. No behavior change on native platforms.
• Test app now runs on all platforms — Web, Windows, and Android from a single test_app/. 22 integration tests covering key generation, client init, DMs, groups, sync, addAccount, and inbox state verification.

1.0.2

• Clarified Windows setup: DLL is not included in pub.dev package, clone repo + build + copy workflow documented
• Updated README and START_HERE with explicit per-platform instructions

1.0.1

• Removed untested macOS and Linux platform declarations
• Fixed lint warnings (unused imports, missing @override annotations, unnecessary type checks)
• Added .gitignore, removed generated files from tracking
