Save Base64 Image to gallery in iPhone/Android

I am trying to save generated qr Code to gallery of mobile, for that i am using Base64ToGallery plugin. Base64ToGallery Plugin is saving image in the following path " /var/mobile/Containers/Data/Application/D453CNA6-ACC1-40F1-916A-D73B5A13975C/Library/NoCloud/_img4622783188.png" in iPhone. But i cant find the image under Photos of iPhone. Following is the code to save image into gallery

save() {
html2canvas(document.querySelector("#screens")).then(canvas => {
  try {
    this.qrCodeGen.base64Image = canvas.toDataURL('image/jpeg', 0.9);
        let options:Base64ToGalleryOptions = { prefix: '_img',mediaScanner: true };
        this.platform.ready().then(() => {

            res => {
              console.log('Saved image to gallery ', res);
            err => {
              console.log('Error saving image to gallery ', err);

     } catch (error) {
          console.log("errorr   ", error);

If anyone did saving base64 string into gallery, it would be nice to get some solutions.

I have the same problem. If anyone find a solution to this, please let us know.
