Need help for Flask-SocketIO and Flutter Client

[amougnom]

Hello,

I have a Flask-SocketIO server (version 5) working fine with Python clients but can't connect with Flutter socketio_client.

According to many posts, it version issues. I downgrade Flask-SocketIO to 4.3.1 and I can connect but Server can't send message to client and I know it's still version problem.

Please here is my inquiries :

1. Which version of Flask, Flask-SocketIO, python-socketio en python-engineio are recommended to support flutter client 2.0.0Beta
2. Which version of Flask, Flask-SocketIO, python-socketio en python-engineio are recommended to support flutter client 1.0.2

Thanks for helping please.

Regards.

I'm sorry, but I cannot answer questions or offer support for the flutter client. I track compatibility against the official JavaScript library, which is the reference implementation.
