Is this extension still supported?

The last release was back in 2018. There are newer versions of boto and flask and this is causing some issues:

flask-boto3 0.3.2 has requirement boto3==1.7.4, but you'll have boto3 1.14.51 which is incompatible.
flask-boto3 0.3.2 has requirement botocore==1.10.6, but you'll have botocore 1.17.51 which is incompatible.
flask-boto3 0.3.2 has requirement click==6.7, but you'll have click 7.1.2 which is incompatible.
flask-boto3 0.3.2 has requirement flask==0.12.2, but you'll have flask 1.1.2 which is incompatible.
flask-boto3 0.3.2 has requirement itsdangerous==0.24, but you'll have itsdangerous 1.1.0 which is incompatible.
flask-boto3 0.3.2 has requirement jinja2==2.10, but you'll have jinja2 2.11.2 which is incompatible.
flask-boto3 0.3.2 has requirement s3transfer==0.1.13, but you'll have s3transfer 0.3.3 which is incompatible.
flask-boto3 0.3.2 has requirement werkzeug==0.14.1, but you'll have werkzeug 0.16.1 which is incompatible.

I can't stay locked on old versions of packages.

I ended up forking and updating the dependencies for my own reference. You could reference my fork as a starting point if it helps. Bear in mind that I usually run the included tests, glance through the changelogs for glaring changes and check that my integration continues to work, but otherwise do not exhaustively check functionality when I upgrade the dependencies.
