Broken import dart:indexed_db in package's Support sound null safety score.

[kithe-raker]

I've just published my first flutter package.
The package was built with dart null-safety, but pub.dev said that my package doesn't support Null safety with Broken import dart:indexed_db issue.

• here is screenshot
• dart pub outdated --mode=null-safety

Showing dependencies that are currently not opted in to null-safety.
[✗] indicates versions without null safety support.
[✓] indicates versions opting in to null safety.

All your dependencies declare support for null-safety.

• dart migrate

See https://dart.dev/go/null-safety-migration for a migration guide.

Any update on this?
I am facing the same issue with my package

[isoos]

In both cases this happens because Flutter seems to block dart:indexed_db, I'm not sure why. I've found this thread which suggest to use package:idb_shim instead:
flutter/flutter#44937

@isoos my package doesn't have a direct dependency on dart:indexed_db. I've even looked into the dependencies and non of them have a reference for dart:indexed_db. Moreover, all the dependencies pub scores don't show this issue.

Here is the list of all the package dependencies:
flutter_bloc: ^7.0.1
hydrated_bloc: ^7.0.1
equatable: ^2.0.3
http: ^0.13.3
meta: ^1.7.0

[isoos]

Yeah, I'm not sure either, I'll need to investigate this a bit...

[isoos]

Extra debugging (exposing it in #922 for users) revealed the following import chain:

• package:bloc_rest_api/bloc_rest_api.dart that imports:
• package:bloc_rest_api/src/cubits/cubits.dart that imports:
• package:hydrated_bloc/hydrated_bloc.dart that imports:
• package:hydrated_bloc/src/hydrated_storage.dart that imports:
• package:hydrated_bloc/src/hydrated_cipher.dart that imports:
• package:hive/hive.dart that imports:
• package:hive/src/object/hive_object.dart that imports:
• package:hive/src/object/hive_list_impl.dart that imports:
• package:hive/src/hive_impl.dart that imports:
• package:hive/src/backend/storage_backend.dart that imports:
• package:hive/src/backend/js/backend_manager.dart that imports:
• package:hive/src/backend/js/storage_backend_js.dart that imports:
• dart:indexed_db where dart:indexed_db is not reachable.

And the reason this is revealed in some packages but not in others:

• dart:indexed_db is inaccessible from Flutter SDK, and packages analyzed with Flutter receive a similar report.
• However, package:hydrated_bloc and package:hive doesn't require Flutter, it is analyzed with Dart SDK, and in those dart:indexed_db is accessible.

In the case of bloc_rest_api it has a Flutter dependency, hence, why it doesn't work.

I guess we should find out if dart:indexed_db works in Flutter Web.
