Go to Routes/client_routes.py you can see which routes and namespaces...
Example : for client_routes.py namespace is '/client' (mentioned in app.py)

You can write class-based namespaces on client side
Example : go to Test/Routes/client_routes.py (this is python implementation)
But I am confident that there would be something like this in dart too

Test

This folder has python-sockets-client code, ignore this
I use this to test my server code

Database
