How can I add image to cache manually.

[un-hongly]

Hi here, I want to add some images to cache manager manually for CachedNetworkImage. My code below doesn't work so what can I do to achieve that?

  // storing cache
  String imageUrl = 'some url';
  String cacheKey = 'some_key';
  DefaultCacheManager cacheManager = DefaultCacheManager();
  await cacheManager.downloadFile(imageUrl, key:  cacheKey);

  // render image
  CachedNetworkImage(
    cacheManager: cacheManager,
    cacheKey: cacheKey,
    imageUrl:  'imageUrl',
  ),
