[firebase_storage] is the gzip file is automatically decompressed when download from firebase storage?

[bigbang489]

My code:

Future<Object> getJSONObject(String path) async {
    final rawData = await FirebaseStorage.instance.ref(path).getData();
    try {
      if (path.endsWith('.gz')) {
        return jsonDecode(utf8.decode(gzip.decode(rawData!.toList())));
      }
    } catch (e) {}
    return jsonDecode(utf8.decode(rawData!.toList()));
  }

My file path ends with .gz, I got Bad Data exception when trying to decode rawData.
The object metadata:
Content-Type: application/json
Content-Encoding: gzip
Cache-Control: no-transform
File size: 10.8KB
I expected the rawDate is compressed file (because Transcode was disabled by setting Cache-Control: no-transform) But the actual format of rawData is text. Does firebase_storage automatically decompress the content?
