Steps to Reproduce
Not sure how. It only happens when the app starts, a box is opened and written to quickly. If I put a breakpoint and it pauses, then when it resumes, the error doesn't show up

On which device does this error happen?

[simc]

What I believe happens: Hive can for some reason not write to the box file (not necessarily a bug in Hive). It then reverts the key transaction to be in sync with the disk. This operation fails (certainly a bug). I'll try to find the reason.

Thanks for reporting. If you find any more information or even a way to reproduce this, please share it here 👍

Thanks. This is being tested on an iOS simulator. It was consistent in my code, which is available at the repo I linked to , however, I removed the class I was using it in because it wasn't necessary for the app. I can point you to the previous commit if you'd really like to see it in action

Sorry this was a bigger problem but it is now fixed with 1.1.0-beta.

[ThinkDigitalSoftware]

Thanks!

@leisim Do we need to clone the repo to get this fix?

[simc]

No you can use version 1.1.0-beta from pub.dev

when i try to write this code in flutter using hive with latest versions.

Product? product = _products.firstWhere((product) => product?.id == productId, orElse: () => null);
if (product != null) {
isExist = true;
}

i am getting error like this

Unhandled Exception: type '() => Null' is not a subtype of type '(() => ApiLogs)?' of 'orElse'
