@felix-mittermeier help ?

This is a problem for me on too on iOS v16.

Crashalytics is reporting this consistently across many users. I've checked the entire codebase to ensure everything is being awaited properly;

I have tried two ways to initialise too;

storage.ready.then((success) =>AppStorage(storage)

and

await storage.ready AppStorage(storage);

[felix-mittermeier]

Just replace the package inside your pub spec.yaml file with

localstorage:
    git:
      url: https://github.com/Ocell-io/flutter_localstorage.git

And the problem should be fixed :-)

[peazz]

Id suggest this is a system level bug then beyond any packages control 🤷‍♂️

[felix-mittermeier]

Not sure what you mean? The issue is that in real life usage two operations at the same time try to read/write something to the local storage. If this happens, the system error is thrown. So in my fork of the package (as mentioned above) I ensured that it will never try to do two operations simultaneously but after each other.

[peazz]

Well you didn’t state it was a fork at all, you just said replace it with this - not very helpful.

I’ve already migrated to shared preferences.

Good luck.

I mean if it has the same package name, then it's always a fork. But sorry, just wanted to help. This issue was already explained multiple times in this issue: https://github.com/lesnitsky/flutter_localstorage/issues/56#issuecomment-800651187

I was tagged in a comment above, that's why I answered 😅

[brenomenosso]

Thank you @felix-mittermeier, because error:

Error (Xcode): lib/services/localstorage_database.dart:1:8: Error: Error when reading '../../../.pub-cache/git/flutter_localstorage-be405ab1476da74ad4ca58458f93bbc7cddd2c02/lib/localstorage.dart': No such file or directory

pod install e pod update ?

[felix-mittermeier]

@brenomenosso Please provide more details what you did, what happened and what you tried. Otherwise I don't think I can help you

[brenomenosso]

I just added the git part as mentioned above to pubspec.... I tried pod install and pod update, because I'm running and testing on an iPhone

[felix-mittermeier]

Normally you don't have to run the pod command newly after changing the package. Did you already try flutter clean and flutter pub get ?

[brenomenosso]

I try, cleaning

[brenomenosso]

not working, import is correct ?

[felix-mittermeier]

Yeah that's correct. Hmm this looks like you pub cache is invalid 🤔

Maybe you can try to delete the pubspec.lock file and then run flutter pub get again.

[brenomenosso]

ok, I will do this

[brenomenosso]

not working. By any chance, do you have a print of your pubspec.lock of what it would look like?

[lesnitsky]

v5 is synchronous now.
