In release mode, when I run my app, if I have the app in the background for around 30 seconds and bring the app to the foreground I get the error-log:

This will result in a grey-screen, freezing the app. Any idea what is causing this error or how to get around it?

I'm using firebase, maybe this is causing it?

    I'm having the same issue, do you find a solution for that ? – Flutter Dev Nov 25 '22 at 16:35
  • Are you tired of this one, by adding the following methods in the app delegate override func applicationDidBecomeActive(_ application: UIApplication) { signal(SIGPIPE, SIG_IGN); } override func applicationWillEnterForeground(_ application: UIApplication) { signal(SIGPIPE, SIG_IGN); } – sunilkumar Feb 02 '23 at 13:29
