vibrate method

void vibrate({ int leftMotorSpeed = 0, int rightMotorSpeed = 0, })

Activate a gamepad controller's vibration motors.

Either the left or right motor can be activated. The value should be between 0 and 65535.

Implementation

void vibrate({int leftMotorSpeed = 0, int rightMotorSpeed = 0}) {
  if (leftMotorSpeed < 0 ||
      leftMotorSpeed > 65535 ||
      rightMotorSpeed < 0 ||
      rightMotorSpeed > 65535) {
    throw ArgumentError('Vibration value must be in range 0..65535');
  }

  using((arena) {
    final pVibration = arena<XINPUT_VIBRATION>();
    pVibration.ref
      ..wLeftMotorSpeed = leftMotorSpeed
      ..wRightMotorSpeed = rightMotorSpeed;
    final dwResult = WIN32_ERROR(XInputSetState(controller, pVibration));
    if (dwResult == ERROR_DEVICE_NOT_CONNECTED) {
      throw DeviceNotConnectedError();
    } else if (dwResult != ERROR_SUCCESS) {
      throw WindowsException(dwResult.toHRESULT());
    }
  });
