Unhandled Exception: FileSystemException: Creation failed, path = 'algolia' (OS Error: Read-only file system, errno = 30)

[Patrick386]

When I run the app on the iOS emulator(iPhone 14), I encounter the following error. Do you know how to resolve it? Just to note, there are no issues when running it on the web.

algolia_helper_flutter: ^0.3.2

I got the same error, after upgrading Flutter to the 3.10.2 version.

This is stack trace from crashanalytics :

Non-fatal Exception: io.flutter.plugins.firebase.crashlytics.FlutterError: FileSystemException: Creation failed, path = 'algolia' (OS Error: Read-only file system, errno = 30) at ._rootRunUnary(dart:async) at BackendManager.open(backend_manager.dart:34) at HiveImpl._openBox(hive_impl.dart:101) at HiveImpl.openBox(hive_impl.dart:142) at UserTokenStorage.read(user_token_storage.dart:101)

This is caused by an issue in how hive is used in https://github.com/algolia/algoliasearch-helper-flutter/blob/main/insights_dart/lib/src/user_token_storage.dart

It seems like that when you create an HitsSearcher you are also forced to instantiate Insight even if you don't actually use it.

The fix is to add a temporary writable directory before opening the box. I'll PR that so that later people can point to that version for the fix.

Hi @Patrick386, @deogw , Thank you for reporting this issue.
I'm actively working to find a solution and fix this as soon as possible.

[nerder]

That's great.

It seems like the solution is simply to do this:

  Future<Box> get _box async {
    final tmpDir = await getTemporaryDirectory();
    return Hive.openBox(_boxName, path: '${tmpDir.path}/$_boxPath');
  }

instead of this:

https://github.com/algolia/algoliasearch-helper-flutter/blob/3e9c5732b61f9749dee0ce1d6fa7d3232a9ae7f6/insights_dart/lib/src/user_token_storage.dart#L41

I've forked the repo and I'm testing this right now.

[nerder]

I've tested it locally and the error is not triggered anymore, as a temporary workaround until the maintainer ship this code you can point at my commit:

pubspec.yml

Same error, is there a timeline as to when the fix will be merged to main and published?
