I'll add some details here.
I am rendering <ImageViewer /> inside a modal window.

 <Modal
          visible={imageViewerModalVisible}
          animationType={"fade"}
          transparent={true}
        >
          <ImageViewer
            index={imageViewerIndex}
            enableImageZoom={true}
            backgroundColor={"rgba(0, 0, 0, .8)"}
            enableSwipeDown={true}
            onSwipeDown={() => setImageViewerModalVisible(null)}
            imageUrls={eventGallery.map((i) => ({ url: i }))}
          />
        </Modal>
        ```
