flask issue when route is in another file circular import

Question

I have a simple app for now

myproject
    ---flask_app
             ----app.py
             ----app_views.py

in my app.py I have

from flask import Flask

app = Flask(__name__)

from flask_app import app_views

in app_views.py I have

from flask_app import app


@app.route('/test')
def home():
    print('im in test route')
    return "hello world!"

when I start it I am getting

File "app_views.py", line 4, in <module>
@app.route('/test')
AttributeError: partially initialized module 'flask_app.app' has no attribute 'route' (most likely due to a circular import)

Please can someone help? If I put the route in app.py it works but I do not want that

Thanks
