Run Flask app with arguments in command line

I have a flask app that works fine. However I need to include arguments when running the app in the command line. I can use python app.py arg1 but when I try using flask run arg1 it throws the error:

Error: Got unexpected extra argument (arg1)

Is there any way to add arguments to the flask run command?

Instead of using flask run you could define your entrypoint like so

import sys
from flask import Flask

if __name__ == '__main__':
  foo = sys.argv[1]  
  app = Flask(__name__)
  app.config['foo'] = foo
  app.run()

However, it's probably wiser to create a custom cli command to take arguments for you and start up the flask app. Read more about custom cli commands here.
