 * on IOS enables blurry view when app goes into inactive state
 */
RNScreenshotPrevent.enabled(true/false);

 * creates a hidden secureTextField which prevents Application UI capture on screenshots
 */
if(!__DEV__) RNScreenshotPrevent.enableSecureView();

/* (IOS) enableSecureView for IOS13+ 
 * creates a hidden secureTextField which prevents Application UI capture on screenshots
 * and uses imgUri as the source of the background image (can be both https://, file:///)

if(!__DEV__) RNPreventScreenshot.enableSecureView(imgUri);

/* (IOS) disableSecureView for IOS13+ 
 * remove a hidden secureTextField which prevents Application UI capture on screenshots
 */
if(!__DEV__) RNScreenshotPrevent.disableSecureView();
