linking web application's backend in python and frontend in flutter
Yes you both can access same Django rest framework Backend. Try searching for rest API using Django rest framework and you are good to go.
Other alternatives are Firebase or creating rest API with PHP.
You would need to define API endpoints for different functions of your app like login,register etc.
Django rest framework works well with Flutter. I have tried it. You could also host it in Heroku
Use http package in flutter to communicate with the Django server.
I am making a CRM web application. I am planning to do its backend in python(because I only know that language better) and I have a friend who uses flutter for frontend. Is it possible to link these two things(flutter and python backend)? If yes how can it be done...and if no what are the alternatives I have?
