Implementation

static Future<bool> evictFromCache(
  String url, {
  String? cacheKey,
  BaseCacheManager? cacheManager,
  double scale = 1,
}) async {
  final effectiveCacheManager =
      cacheManager ?? CachedNetworkImageProvider.defaultCacheManager;
  await effectiveCacheManager.removeFile(cacheKey ?? url);
  return CachedNetworkImageProvider(url, scale: scale).evict();
}
