How to use tqdm's wrapattr with tarfile?

Question

Using tqdm to get a progress bar while downloading a file is very nice. For example I found this answer

import requests
from tqdm.auto import tqdm

eg_link = "https://github.com/tqdm/tqdm/releases/download/v4.46.0/tqdm-4.46.0-py2.py3-none-any.whl"
eg_file = eg_link.split('/')[-1]
response = requests.get(eg_link, stream=True)
with tqdm.wrapattr(open(eg_file, "wb"), "write", miniters=1,
                   total=int(response.headers.get('content-length', 0)),
                   desc=eg_file) as fout:
    for chunk in response.iter_content(chunk_size=4096):
        fout.write(chunk)

However, I am wondering how it would work for a .tar.gz file? How do I know the length of the file? How to extract it "iteratively"?

import tarfile
with tarfile.open(file_path, "r:gz") as tar:
    tar.extractall(output_dir)
