whatsapp-clone-flutter's Issues

Flutter App is not working for Dart 3

Hello,
I wanted to follow your programm sessions to programm my own Chat App. But your instructions are most of the time not working because it is not compatible with Dart 3. Could you please update the Code? Furthermore some Package like the one for Emojis are not Dart 3 compatible

not all file found

socket io client connection to backend

I clown your repository to see if the connection issue is from my code, but no joy as the connection still returns false everything I connect it to my backend even though the backend is running. Any idea what to do? Thank you for your great tutorial.
