@renysh i fixed my problem by using 2.0.0-beta.4-nullsafety.0 version dont use version 1.0.2 socket_io_client: ^2.0.0-beta.4-nullsafety.0

I can confirm that using the 2.0.0 pre release version fixed my problem when using "socket.io": "4.5.1",

HI, can you please confirm whether when internet connection is turned off and then on, does it connect to the existing last socket connection (on a real physical device)?

For me, on emulator, the socket reconnects when internet is back on (as expected), but on a physical device it just throws SocketException immediately after internet disconnects (No such exception when turn off internet in android emulator)

I have same problem. I using socket_io_client: ^2.0.0-beta.4-nullsafety.0 and Flask-SocketIO 5.3.2 but it still can’t connect in Real Device.
