var inputImage: UIImage {
    return UIImage(named: "demo") ??  UIImage(systemName: "sun.haze.fill")!

        Button(action: {
            self.showCropView = true
        }) {
            Text("Show the crop view")
        }
        
        if self.croppedImage != nil {
            Image(uiImage: self.cropedImage!)
                .resizable()
                .scaledToFit()
                .padding()
        }
    }
    .sheet(isPresented: $showCropView,onDismiss:finishedCrop ) {
        CropImageView(inputImage: self.inputImage, resultImage: self.$croppedImage, cropSize: CGSize(width: 250, height: 250))
