[diybl]

when the remote reboot or shutdown

the done handler not working.
`await session.done;

client.close();
await client.done;`

the error is.

[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: SSHStateError(Transport is closed)

void sendPacket(Uint8List data) {
if (isClosed) {
return;
throw SSHStateError('Transport is closed');
}

i add return before throw SSHStateError('Transport is closed');
and then temporary solve.

I have the same error except the error occurs when I connect to my Cisco catalyst switch 2960 serires in the first run I get the result then when using the same client one more time to excute the same command it says :

SSHStateError(Transport is closed)

My Code :

static cisco(SSHClient client) async {
    await client.ping();
    print(await client.run('show env fan'));
    await client.ping();

}

BTW : the same code runs on all other devices very well
