Stale period not working properly

` Im using **flutter_cache_manager: ^3.3.1** and the stale period its not working properly. its not automatically deleting the files.

final cacheManager = CacheManager(
Config(
id,
stalePeriod: Duration(seconds: 60),
maxNrOfCacheObjects: 10,
),
);

try {
final fileStream = cacheManager.getFileStream(_syncMusicUrl);

await for (var response in fileStream) {
if (response is FileInfo) {
_cacheMusicPath = response.file.path;

return true;
} else if (response is DownloadProgress) {}
}
return false;
} catch (error) {
syncSituation.value = "sync";
update();
return false;
} }`

Start by reproducing the report with flutter_cache_manager 3.3.1, a 60-second stalePeriod, and getFileStream as shown in the issue. Trace the cache cleanup behavior from this usage and verify that cached files are removed after the configured stale period.
