  const onChange = (imageList, addUpdateIndex) => {
    // data for submit
    console.log(imageList, addUpdateIndex);
    setImages(imageList);

        {({

          onImageUpload,
          onImageRemoveAll,
          onImageUpdate,

                style={isDragging ? { color: 'red' } : undefined}
                onClick={onImageUpload}

                </div>
              </div>
            ))}
          </div>
