@Mocaris & @eldarkk, Thank you for bringing this to our attention. I can not get the same the error so I was wondering if you could provide us some more information.

Can you send a code snippet so we can reproduce the same issue, and can you also send your plist.info file? That would be much appreciated, thanks in advance!

This error occurred when I started the App after updating macOS to 11.5, and the flutter-permission-handler 8.1.3->8.1.4. After I removed the flutter-permission-handler dependency, the project worked fine

[Mocaris]

@Mocaris & @eldarkk，感谢您提请我们注意此事。 我无法得到同样的错误，所以我想知道您是否能向我们提供更多的信息。

Can you send a code snippet so we can reproduce the same issue, and can you also send your plist.info file? 非常感谢，提前感谢！

We have the same mistake @eldarkk

[JDDV]

@Mocaris and @eldarkk, this the same issue occur if you go back one version of the permission handler in the pub spec.yaml (version ^8.1.3)?

Also to make sure there is no caching problem try to run a flutter clean and then a flutter pub get to get the dependencies.

There is no problem with the 8.1.3 version used yesterday, because I submitted the packaged version to TestFlight. This problem occurred after the 8.1.4 version was upgraded

[Mocaris]

@JDDV Thanks

[JDDV]

@Mocaris & @eldarkk, you can safely use the newest version which just is published (version ^8.1.4+1). There was a small bug where the code

else if (status != PermissionStatusDenied) {
        completionHandler(status);
    }

did not have a return; statement, so it would go further to the requestAlwaysAuthorization while the _permissionStatusHandler was already removed from the memory, resulting in the error as shown in your images. this is fixed now by adding a return; statement in the code.

This solved the problem for us, I will close this issue now but please feel free to comment again if it did not solve your problem!

[WXXXXH]

@Mocaris & @eldarkk，您可以安全地使用刚刚发布的最新版本（版本^8.1.4+1）。代码有一个小错误

else if (status != PermissionStatusDenied) {
        completionHandler(status);
    }

没有return;语句，所以当_permissionStatusHandler已经从内存中删除时，它会进一步转到requestAlwaysAuthorization，导致图像中显示的错误。现在通过在代码中添加return;语句来解决这个问题。

这为我们解决了问题，我现在将解决这个问题，但如果它没有解决您的问题，请随时再次发表评论！

[JDDV]

Hi @WXXXXH, Can you provide us with a bit more information? Like when does this error happen for you and which permission did you try to request before getting this error?

Can you provide a small minimal reproduction code snippet so I can see where this error is coming from?

Thanks in advance!
