    override fun onGenericMotionEvent(event: MotionEvent?): Boolean {

            WearableRotaryPlugin.onGenericMotionEvent(event) -> true
            else -> super.onGenericMotionEvent(event)
        }
    }
}

Usage

To use this plugin, add wearable_rotary as a dependency in your pubspec.yaml file.

dependencies:
  wearable_rotary: ^2.0.1

Then, import wearable_rotary in your Dart code.

// Import the package.
import 'package:wearable_rotary/wearable_rotary.dart';

// Be informed when an event (RotaryEvent.clockwise or RotaryEvent.counterClockwise) occurs.
StreamSubscription<RotaryEvent> rotarySubscription =
    rotaryEvents.listen((RotaryEvent event) {
  if (event.direction == RotaryDirection.clockwise) {
    // Do something.
  } else if (event.direction == RotaryDirection.counterClockwise) {
    // Do something.
  }
});

// Be sure to cancel on dispose.
rotarySubscription.cancel();

// Use [RotaryScrollController] to easily make scrolling widgets respond to rotary input.
ListView(controller: RotaryScrollController());
