Connection problem

[Adidi]

I have tried several approaches - the connection to pubnub in some point (even if the app is active and there is internet connection) is disconnected and really really unstable - i cant get 3 devices "chatting" for more then 2 min without some connection drop: and the worst thing is i dont have any indication from the sdk that its happening so i cant do anything to restore it. This is a really big problem if u design chat system and really unreliable solution for me this is the log:

Thank you very much but I am afraid dart sdk is still not mature enough

We actually have a bug fix in the release process for the error that you experiencing.

Apart from that, I'm sorry that you feel this way. We want to make sure that the Dart SDK is the best it can be.

[Adidi]

I want that too. Can u tell me when the fix should be released ? I think its pretty basic wanting a stable connection for 3 min :) dont u think ?

[are]

Fix will be released this week. It is a regression since connection was stable and tested before.

[Adidi]

@are any updates ?

[Adidi]

And I am asking again - is there any updates on this ? @are

[are]

Dart SDK v3.2.0 will be released today.

[are]

Fix for this has been released in 3.2.0.

[Adidi]

@are Nope. It still happening - connection is not stable at all in iphone and in android. Well - it was a fun ride but i think i will move on to some other solution because cleary dart pubnub is not stable enough to go production - I am sure one day it will be - good luck !

Please next time either report the issue with a reproducible example or logs attached. I also recommend contacting support.
