skio_core 0.1.0-beta.1

Shared pure-Dart types for the skio Flutter hardware plugins: permission access status, a sealed hardware exception family and USB/BLE device filters.

skio_core

Shared pure-Dart types for the skio Flutter hardware plugins: one permission API, one error family and one way to match devices across USB serial and UVC cameras. No Flutter dependency and no platform code.

You normally don't depend on this package directly. Each skio plugin re-exports it.

Beta. The API may still change before 0.1.0.

import 'package:skio_core/skio_core.dart';

const filter = DeviceFilter(vendorId: 0x10c4, productId: 0xea60);

try {
  // ... call any skio plugin
} on HardwareException catch (e) {
  switch (e) {
    case AccessDenied():
      // ask the user again, or point them to settings
    case Disconnected():
      // show "reconnect the device"
    default:
      print(e.message);
  }
}
