SocketException: Connection timed out (OS Error: Connection timed out, errno = 110), address = 192.168.1.88, port = 45118

I am getting this error when testing my Flutter application on a real device:
SocketException: Connection timed out (OS Error: Connection timed out, errno = 110), address = 192.168.1.88, port = 45118

But it works fine on a emulator. Only getting this error on a real device.
