I am developing a mobile application using Ionic 4. Everything is working smoothly, but i could not save the picture when i call the function takePicture(). Does it have any parametes like saveToPhotoAlbum like Ionic Camera Plugin. Do help me out.

  cameraPictureOpts: CameraPreviewPictureOptions = {
    width: window.innerWidth,
    height: window.innerHeight,
    quality: 100
  }

  takePicture() {
    let result = this.cameraPreview.takePicture(this.cameraPictureOpts);
    let picture = `data:image/jpeg;base64,${result}`;
  }
