// HACK if current is in animation don't start gesture
if (!this.props.transitionProps.position._animation) {

}
// Switch to using gesture position
this.positionSwitch.setValue(0);
// By enabling the gesture switch and ignoring the position here we
// end up with a quick jump to the initial value and then back to the
// gesture. While this isn't ideal, it's preferred over preventing new
// gestures during the animation (all gestures should be interruptible)
// and we will properly fix it (interruptible and from the correct position)
// when we integrate reanimated. If you prefer to prevent gestures during
// transitions, then fork this library, comment the positionSwitch value set above,
// and uncomment the following two lines.
// if (!this.props.transitionProps.position._animation) {
// this.positionSwitch.setValue(0);
// }
