Error after bind resource - Unhandled Exception: Bad state: Cannot add event after closing

[TatankaConCube]

Hello guys, you are cool team and you did big work for implementation xmpp protocol on dart. Today I updated xmpp_stone to lates version (0.2.2) and I got unexpected issue, below detaile information about it.

Version: 0.2.2 Code to reproduce:

import 'package:xmpp_stone/xmpp_stone.dart' as xmpp;
...

String userJid = ""; // full user jid
xmpp.XmppAccountSettings accountSettings = xmpp.XmppAccountSettings.fromJid(userJid, password);

xmpp.Connection  _connection = xmpp.Connection.getInstance(accountSettings);

_connection.connect();

Looks like server closed the socket and lib is trying to use it. Can you please check is this reproducible for you with 0.2.1?

[TatankaConCube]

Please wait few minutes, I should rebuild project and collect logs. FYI: In version 0.1.5 it worked fine, but was issue after logout and login again, if need I will collect needed logs.

[TatankaConCube]

I got the same error in version 0.2.1 (((

[vukoye]

Thanks, sorry to hear that, I will try to figure out what's going on.

[TatankaConCube]

one moment, please, looks like I was mistake when changed version to 0.2.1, but flutter used 0.2.2, I will clean caches and answer later.

[TatankaConCube]

I got next error when change version to 0.2.1, can you please help me to resolve it

Because every version of xmpp_stone depends on image ^2.0.7 which depends on xml ^3.2.5, every version of xmpp_stone requires xml ^3.2.5.

So, because app depends on xmpp_stone 0.2.1 which depends on xml ^4.1.0, version solving failed.
pub upgrade failed (1; So, because app depends on xmpp_stone 0.2.1 which depends on xml ^4.1.0, version solving failed.)

[vukoye]

Sorry for tht. 0.2.1 had some dependency issues, try 0.2.0

[TatankaConCube]

The same issue in version 0.2.0 ((( But in logs I can see incoming packages, looks like connection was established but callback XmppConnectionState.Ready wasn't called.

[TatankaConCube]

If you, guys need any help for testing this issue, you can ask me and I will try to help you.

[vukoye]

One more question, if you have some test accounts for your server, can you please sent it to my email address nemanja.vukoje@gmail.com I can not reproduce it on mine, it will be easier to fix the issue.

[TatankaConCube]

I sent needed informations on your e-mail, thank you for support.

[vukoye]

Can you please check the latest version 0.2.3?

[TatankaConCube]

@vukoye thank you for your support, now login works fine. But now I have another issue, I will create new ticket.
