1.0.1 - 2026-02-16

• Connection types: Updated connection type

1.0.0 - 2026-02-11

Added

• Connection types: Initialize and connect over Serial port, USB, or BLE (initDevice, openScale with path / index / address).
• Device list: getDeviceList() for paths (serial), USB indices, or BLE addresses.
• Connection lifecycle: openScale, closeScale, isConnected. Events: connected, disconnected, usb_attached, usb_detached, error, crash.
• Live weight: startLiveWeight / stopLiveWeight; weight events on eventStream when live weight is started.
• One-shot weight: getWeight() to read current weight once.
• Scale commands: zero(), tare(), setTarePre(value), setFrequency(index) (weight must be stable for zero/tare where required by the scale).
• Ensure-connection helpers: getWeightEnsuringConnection() and startLiveWeightEnsuringConnection() — when not connected, refresh device list and connect to the first available device, then get weight or start live weight (no stored path/index; suitable when path or index may change after unplug/plug).
• Connection type: getConnectionType() to read the current type (serial / usb / ble) set by initDevice.
• Native crash reporting: Plugin sends crash events to Flutter (message, stack trace, exception type) so apps can report to Crashlytics or other services.
• Android: Full integration with ACLAS SDK (AclasScaler), including background-thread connect, weightInfo.init() before connect, AclasReset() on connection success, BLE connect by list index, and defensive handling of listener and event channel calls.

Notes

• Android only in this release. Requires ACLAS SDK artifacts (JAR and jniLibs) in the plugin’s android/libs/ and android/src/main/jniLibs/ (see README).
• If using ProGuard/R8 (minify/shrinkResources), add keep rules for the ACLAS SDK to avoid runtime crashes; see README.
