1.0.0 #

  • First stable release — all 27 ITU-R M.1371 message types implemented and tested.
  • Added working pub.flutter-io.cn example (example/example.dart).
  • Expanded documentation and API dartdoc comments across all public types.
  • Stable public API: AISMessage.fromString() and AISMessage.fromPayload() are considered stable going forward.

  • Completed implementation of all 27 ITU-R M.1371 message types, covering position reports (Types 1–3, 9, 18, 19, 27), static & voyage data (Types 5, 24), binary messages (Types 6–8, 25, 26), network messages (Types 10, 15–17, 20, 22, 23), safety messages (Types 12–14), and specialized reports (Types 4, 21).
  • Added unit tests for every supported message type using real-world AIS data.

0.1.1 #

  • Replaced the original string-based binary decoding algorithm with a direct bit-manipulation approach, significantly improving decoding performance.
