@renefloor I actually still get this error. I'm on version 2.1.2 but I see this fix was submitted way before that release. I don't do any explicit deleting on my end so I think it has to be a library bug? My stacktrace is:

FileSystemException: FileSystemException: Cannot delete file, path = '/var/mobile/Containers/Data/Application/6867986F-318E-4E1D-AF0D-EA736FDD62C7/Library/Caches/audioCache/fc00b6f0-a082-11eb-8599-91285352f656.file' (OS Error: No such file or directory, errno = 2)

I also upgraded and get this issue 3.0.1 as well

[renefloor]

@tamoyal can you create a reproducable example?

I also upgraded and get this issue 3.3.0 as well

@renefloor Is a similar problem recurring?

#4 CacheStore._removeCachedFile (package:flutter_cache_manager/src/cache_store.dart:190)

flutter_cache_manager/flutter_cache_manager/lib/src/cache_store.dart

Lines 183 to 186 in 205387b

	final file = await fileSystem.createFile(cacheObject.relativePath);
	if (await file.exists()) {
	await file.delete();
	}

L185 => L190

I see that there is already a judgment on whether the file exists, I don't know why this error still occurs

Im facing this with:

• Cached network image 3.2.1 (which is the last one at the moment) and it internally uses flutter_cache_manager 3.3.0)

I got this error today, although I only could save this image:

There isn't an error stack other than what is displayed in the image

Hi to all

I caught the exception while debugging and got some info (I apologize for sharing the screenshots):

• Where the exception was thrown:
  

• The parent caller:
  

It seems that after checking that the file exists… it got removed before removing it? 👀

@renefloor friendly reminder 👀
