Upgrade to latest Flask version

[mariobehling]

Flask has been released in version 2 for some time now. Please upgrade the system to use flask 2.

[shivam5522]

Should I upgrade it to the latest version? And should I upgrade the dependencies around flask(eg: Flask-login, Flask-script) or only the flask version itself?
Thank you

I think it is not easy to upgrade, related to issue found in #8077.
