RotationController constructor

RotationController()

RotationController

The RotationController provides the values of the device's position sensor.
(Rotation only, without geomagnetic)

Notice

• Sensor data is sent only in the AppLifecycleState.resumed state.
• Constructor implemented in the singleton pattern.
• Because it is implemented in a singleton pattern, the dispose method of the controller is implemented to not work.
• For performance, please call removeListener, dispose (option) when deleting a widget.

Implementation

factory RotationController() {
  return _instance;
}
