JavaScript error on laptop sleep only in release web build

Open DmitrySikorsky opened this issue 2 years ago • 2 comments

Hi! Thank you for your package, it is very useful.

But I have a strange problem. When I sleep my laptop, after that websocket fails to reconnect with JavaScript exception:

If I click the first line I will see this code:

So I think the problem is in this function:

https://github.com/jamiewest/signalr_core/blob/main/lib/src/hub_connection.dart#L383

But if I build the web app like

flutter build web --profile --source-maps

everything works, websocket is reconnected without problems.

At the same time, reconnection works well if I just put the app without interactions, Chrome will reduce setInterval time, and server kills the connection. But if the laptop gets sleep, after that reconnection always fail on release build.

Flutter 3.7.0, package version is 1.1.1.

So, this is really very strange. But I copied your package locally and changed the hub_connection.dart file a little bit.

I only changed the _completeClose function's parameter name to exception1, and the _reconnect function's parameter name to exception2, and now everything works.

I will appreciate if you could find time and release an update that will fix this weird bug that is related, how I think, to JavaScript minification process.
