Hi @TramPamPam
when are you calling connectUser?
It looks like the StreamChat widget is calling connectUser after the app goes in foreground from background and you're calling connectUser too. That's why there are two calls to connectUser

TramPamPam · 2021-07-07T08:11:59Z

Hi @imtoori

We have system popup where we ask for some permissions that are required by our app logic while we connecting user to GetStream.

It's right after we retrieved a token for user, that we use for connect method.

Why does StreamChat tries to connect before we use connect user manually?

imtoori · 2021-07-07T10:19:53Z

ok apparently the system pop up makes the StreamChat widget think it's in background and when you close it it comes back to foreground
we check that the client.wsConnectionStatus is disconnected before opening the connection (you can see this here)

Can you enable the client logs with info level and paste it here?

Hi @TramPamPam do you have the StreamChat widget on top of the Navigator/MaterialApp?
How are you using it?

TramPamPam · 2021-07-13T11:09:54Z

Hi @imtoori

Like this:

 static late StreamChatClient client = StreamChatClient(
    EnvironmentConfig.GETSTREAM_PROJECT_ID,
    baseURL:
        'chat.stream-io-api.com', 
    logLevel: Level.INFO,
  )..chatPersistenceClient = StreamChatPersistenceClient(
    logLevel: Level.INFO,
    connectionMode: ConnectionMode.regular,
  );

MaterialApp(   
      builder: (context, child) => StreamChat(
        streamChatThemeData: StreamChatThemeData.fromTheme(baseTheme),
        client: ChatService.client,
        child: appOverlayBuilder(context, child), //TransitionBuilder
      ),
    );

imtoori · 2021-07-16T10:50:12Z

the merge pr should fix the issue
let us know if that works
you'll find it in the next release

akul1994 · 2021-12-15T10:54:01Z

This issue seems to have resurfaced in 3.3.2,
Can you please check?

imtoori · 2021-12-17T09:04:35Z

Hi @akul1994 can you be more specific? I tested this behaviour and it's working fine for me

akul1994 · 2021-12-17T10:16:56Z

In my app, when the user logs out, I call stream disconnect, and post login and make another call to connectUser with new user credentials.

I put up a listener wsConnectionStatusStream and noticed that after I disconnect User and take him to the login page where my Google Login popup is shown, I'm getting connecting as a status in the connectionStatusStream even though I have not made any calls to connectUser,

As a result, after login when I make a call to connectUser I get an exception saying connect called twice.

akul1994 · 2021-12-17T10:18:15Z

As a workaround, if after logout I reinstantiate the StreamClient object, I don't face this issue, but doing that is causing a few other things to break

imtoori · 2021-12-17T10:36:55Z

@akul1994 I'm testing this using our sample app and it's working fine
How do you disconnect the user?

akul1994 · 2021-12-17T10:41:10Z

    if (client == null) return;
    try {
      await client?.disconnectUser(flushChatPersistence: true);
      client?.removeDevice(PrefRetreiver.fcmToken);
    } catch (e, s) {}
    return;
  }

Like this.

So here are my findings,

After logout if I don't open google popup it doesn't move to a connecting state, as soon as I do it shows a connecting state
In my previous implementation I was awaiting on Stream Connect to proceed from the Splash Screen, However in my current implementation I let it happen async and let the user proceed on the app, I hide the UI components that need StreamConnect to happen till I get a succesful connectUser callback.
In my previous implementation where I was awaiting connectUser I'm not facing this issue, but in my new flow I am. Could this be related to a context in any way?

akul1994 · 2021-12-19T05:17:41Z

@imtoori Any update on this?

imtoori · 2021-12-20T10:44:21Z

hey @akul1994
can you show me how do you're using the StreamChat widget?
Sorry, I'm trying to understand what's going on, this is very weird

akul1994 · 2021-12-20T13:39:13Z

In m main.dart ,
Like this:

StreamChat(
        streamChatThemeData: StreamThemesHelper.getStreamTheme(context),
        client: StreamHelper.client!,
        child: MaterialApp(
          navigatorKey: navigatorKey,
          title: 'threedots',
          theme: AppThemes.appTheme,
          onGenerateRoute: NavigationHelper.generateRoute,
          onGenerateInitialRoutes: (String initialRouteName) {
            return [MaterialPageRoute(builder: (_) => LoginScreen())];
          },
          navigatorObservers: [
            EventsHelper.observer!,
          ],
        ),
      ),
      ```

akul1994 · 2022-01-07T06:57:34Z

Hey @imtoori any update on this, this is happening on every login, logout of the app,
socket moves to disconnected state after logout and as soon as a google popup is shown it moves to a connecting state even without calling connect causing a failure when I actually call connect

imtoori · 2022-01-10T16:05:26Z

Hi @akul1994 I'm sorry but I was out sick
Could you create a sample app for this issue?
I tried reproducing this and I failed. Having a common code could help solve the issue, what do you think?

akul1994 · 2022-01-13T10:52:48Z

Sure, I'll get something setup and get back to you.

As a workaround,
If I reinitialise the stream client after logout, it does not go to connecting state once the google popup shows,

no-response · 2022-02-25T09:11:42Z
