1. wifi working fine both android and ios
2. Cellular data fine on android but iOS 50% when I turn airplane mode on then off then turn cellular on (Wifi 100% off) I receive error: SocketException: Connection failed (OS Error: Network is unreachable, errno = 51), address = 11.111.222.33, port = 3306.
3. Flutter 3.16.9 and I build minimum iOS >= 13.

This error is caused by the socket connection not being closed properly. It is a problem with Dart's underlying code. I recommend detecting a no-network state and actively closing the MySQL connection. Or use try catch?
