can_usb changelog | Flutter package

0.1.3 #

feat(CMD_CAN_START): add configurable FDCAN bitrate selection to canStart(). The command now sends two additional payload bytes — arbitration-phase index (Payload[1]) and data-phase index (Payload[2]) — matching the updated CMD_CAN_START (0x01) spec in FRAME_SPECIFICATION.md.
feat: add ArbBitrate and DataBitrate enums (lib/src/models/bitrate.dart) with one value per supported firmware bitrate setting.
CanusbDevice.canStart() now accepts optional arbBitrate and dataBitrate named parameters; defaults to ArbBitrate.rate1000k / DataBitrate.rate2000k.
Export the new bitrate.dart model from the package entry point.

feat(Android): add AndroidSerialTransport — new ISerialTransport implementation for Android using the USB Host API (usb_serial package). CanusbDevice now auto-selects AndroidSerialTransport on Android and SerialPortTransport on all other platforms.
fix(SerialPortTransport): null _port in onError so isConnected returns false immediately on physical USB removal (Windows).
fix(SerialPortTransport): explicitly close the OS serial handle in onError so Windows releases the COM port and allows re-open after the device is plugged back in.

Metadata fix: shortened pubspec.yaml description to comply with pub.flutter-io.cn 60–180 character limit (no functional changes).

Initial release.
Serial transport layer via flutter_libserialport (SerialPortTransport).
Injectable ISerialTransport interface for easy unit-test mocking.
Binary frame builder (buildFrame) and streaming frame parser (FrameParser).
CRC/checksum implementation matching the device frame specification.
Commands: Get Device ID, CAN Start, CAN Stop, Send Downstream (TX), Send Upstream (RX), Protocol Status, Get/Reset CAN Stats, Enter DFU.
High-level CanusbDevice API with broadcast streams for received frames, protocol status notifications, and CAN stats notifications.
Typed exception hierarchy: CanConnectionException, CanTimeoutException, CanChecksumException, CanProtocolException.
