how to clear cache in CachedNetworkImage flutter

I agree with MichaelM, Don't use CachedNetworkImage.If you show image like this :

Image.network(
      _headImageUrl,
      fit: BoxFit.fitHeight,
    )

you can use those code to clean image cache:

PaintingBinding.instance.imageCache.clear();

Firstly add the package (flutter_cache_manager) to pubspec.yaml file as following:

dependencies: flutter: sdk: flutter flutter_cache_manager: ^1.1.3

After a day, I found the solution. Use the DefaultCacheManager object by calling emptyCache() method, this clears the cache data.

DefaultCacheManager manager = new DefaultCacheManager();
manager.emptyCache(); //clears all data in cache.

Since CachedNetworkImage version 2.3, all these solutions won't work because it cached images in 2 different places (DefaultCacheManager & NetworkImageProvider)

So the only solution is using the evictFromCache built-in method from CachedNetworkImage

like this:

Future _deleteImageFromCache() async {
    String url = "your url";
    await CachedNetworkImage.evictFromCache(url);
  }

evictFromCache is a Static method so it doesn't require to have the CachedNetworkImage in your Widget tree, you can use it directly from any place.

import 'package:flutter_cache_manager/flutter_cache_manager.dart'; await DefaultCacheManager().removeFile('YOUR_URL');

DONT USE emptyCache() from the first answer, it clear ALL your Cache
