Hi I was to reset the zoom level.The use case for which I am trying to do is If the view is already zoomed In and then user double tab the view it should reset to initial zoom level but is is not working as expected.Can you please suggest any solution.

<ReactNativeZoomableView
   maxZoom={1.5}
   minZoom={1}
   zoomStep={0.5}
   zoomEnabled={this.state.isEnabledZoom}
   initialZoom={this.state.initialZoom}
   bindToBorders={true}
 onDoubleTapAfter={(event, gestureState, zoomableViewEventObject)=>{

    if(this.state.initialZoom>1){
     this.setState({ initialZoom: 1,isEnabledZoom:false, scroll:true })
     }else{
     this.setState({ initialZoom:zoomableViewEventObject.zoomLevel,isEnabledZoom:true })
     }/>

This is what I am currently doing. Thanks
