Disable vibration when scanner is not active

When reactivate is set to false, after the first scan, each time a qr code is scanned, the phone vibrates, and the user might think they’re actually scanning something.

agree with mamodom. _handleBarCodeRead(e) {

if (!this.state.scanning) {
  Vibration.vibrate();
  this._setScanning(true);
  this.props.onRead(e)
  if (this.props.reactivate) {
    setTimeout(() => (this._setScanning(false)), this.props.reactivateTimeout);
  }
}
return;

}

move Vibration.vibrate(); into if condition will be good.
