Hello! I have a doubt about cacheKey.

extended_image_library/lib/src/_extended_network_image_utils_io.dart

Lines 31 to 62 in 5847a6a

	/// Clear the disk cache image then return if it succeed.
	Future<bool> clearDiskCachedImage(String url, {String? cacheKey}) async {
	try {
	final File? file = await getCachedImageFile(url, cacheKey: cacheKey);
	if (file != null) {
	await file.delete(recursive: true);
	}
	} catch (_) {
	return false;
	}
	return true;
	}
	/// Get the local file of the cached image
	Future<File?> getCachedImageFile(String url, {String? cacheKey}) async {
	try {
	final String key = cacheKey ?? keyToMd5(url);
	final Directory cacheImagesDirectory = Directory(
	join((await getTemporaryDirectory()).path, cacheImageFolderName));
	if (cacheImagesDirectory.existsSync()) {
	await for (final FileSystemEntity file in cacheImagesDirectory.list()) {
	if (file.path.endsWith(key)) {
	return File(file.path);
	}
	}
	}
	} catch (_) {
	return null;
	}
	return null;
	}

I'd need to save many images to disk and then delete them all at once without passing their urls.
I thought that cacheKey was intended for that purpose, like assigning to [url_1..url_100] the same cackeKey (ie. "profiles") and then clearDiskCachedImage("profiles") to delete from disk all these 100 files that were cached when loading profiles screens.

But from code above, it doesnt seem to work this way. Can you please shed some light on this?
Thx
