not empty my cache directory

DefaultCacheManager().emptyCache();

also this not working any idea

Future _deleteCacheDir() async {
final cacheDir = await getTemporaryDirectory();
if (cacheDir.existsSync()) {
cacheDir.deleteSync(recursive: true);
}
}

Start by reproducing DefaultCacheManager().emptyCache() and the _deleteCacheDir() example using getTemporaryDirectory(). Check whether the temporary cache directory and its contents are removed; done means the cache is empty after the operation completes.
