Error flask_gravatar with flask 3.0.0

[Canfry]

Trying to use flask_gravatar in my project but have the following error when running the app with Gravatar:
ImportError: cannot import name '_request_ctx_stack' from 'flask'

• Python version: 3.12
• Flask version: 3.0.0
• flask_gravatar version: 0.5.0
  The whole app is working perfectly until I use the documentation exemple:
  from flask_gravatar import Gravatar

gravatar = Gravatar(app, size=100, rating='g', default='retro', force_default=False, force_lower=False, use_ssl=False, base_url=None)

I am currently experiencing the same issue, after upgrading Flask to version, 3.0.0. i guess the flask_gravatar 0.5.0 is not compatible with it. Have you found any solution to this problem since?

Well i found a solution, remove anything flask_gravatar from your code and define gravatar as a function instead and integrate into your html. here is the function example:

def gravatar_url(email, size=100, rating='g', default='retro', force_default=False):
hash_value = md5(email.lower().encode('utf-8')).hexdigest()
return f"https://www.gravatar.com/avatar/{hash_value}?s={size}&d={default}&r={rating}&f={force_default}"

This overrides the default function, so its now a custom function

i hope that helps you

Thank you so much yes it works like this 👍👍👍👍

Gravatar is a pretty common tool that more Flask folks are going to want to use in updated Flask versions.
If we could get some traction on this that would be great!
I would also be happy to help contribute if I could.

This worked for me, but I had to use sha256 following this gravatar doc
