    What flutter version are you on ? A similar issue was reported but wasn't replicable on latest beta and master (#94695 (comment)), so I suggest you to upgrade to their latest version and confirm if this behavior still occurs.

    Fix By adding this WidgetsFlutterBinding.ensureInitialized(); to the main function inside main file.

    It is happening to me as well. I could not find the cause, it happens randomly when switching windows.

    I'm seeing something very similar on Linux, with the following stack trace:

    The mention of window switching reminds me of #90838, but the error logs are different. Would appreciate if someone investigates into reproduction.

    @elham-rababah @efreibe Can you provide a complete minimal reproducible code sample along with steps to replicate this error ?

    Without additional information, we are unfortunately not sure how to resolve this issue. We are therefore reluctantly going to close this bug for now.
    If you find this problem please file a new issue with the same description, what happens, logs and the output of 'flutter doctor -v'. All system setups can be slightly different so it's always better to open new issues and reference the related ones.
    Thanks for your contribution.
