rosbridge_dart_client 0.1.1

Subscribe-only Dart client for rosbridge_suite — ROS 2 topic JSON streams over WebSocket. Pure Dart, no transport-layer lock-in.

Changelog

0.1.1

• Republish from the embedded-target Dart 3.10.1 SDK (Flutter 3.38.3) to correct a stale ^3.11.0 SDK floor in the previously-published artifact. No source or behavior change; the source already declared sdk: ^3.10.0. Restores pub get for embedded/automotive Dart consumers on Dart 3.10.x.

0.1.0 — 2026-05-10 — Initial subscribe-only client

• RosbridgeClient: WebSocket client + subscribe Stream multiplexer. Connects to a rosbridge_server ROS 2 node and surfaces topic- subscribe streams as Stream<Map<String, dynamic>>. Caller maps the maps to typed records (e.g. via Nav2CollisionMonitorState.fromJson from nav2_safety_layer).
• RosbridgeProtocolException / RosbridgeTransportException: caller-side discriminable error types for server-reported protocol errors vs WebSocket transport-layer failures.
• Four supported op types: subscribe (outbound), unsubscribe (outbound on Stream cancel), publish (inbound topic message payload), status (inbound protocol notifications).
• Tests run against a synthetic in-process WebSocket channel (StreamChannelMixin + dev-only stream_channel dep); CI does not require a ROS bridge server.

Out of scope for 0.1.0
