Dart null safety

[vaind]

Any timeline for providing null-safety to the dart package? https://medium.com/dartlang/announcing-dart-null-safety-beta-87610fee6730

[vaind]

Any plans with this one?

[gedw99]

me too. This is really needed.

Protobuf has been upgraded already: https://pub.dev/packages/protobuf

BTW I've prepared a null-safe version in our ObjectBox fork of FlatBuffers (https://github.com/objectbox/objectbox-dart/tree/main/objectbox/lib/flatbuffers). It includes a lot of performance improvements/fixes, some of which were originally prepared by @mraleph in separate discussions (basically this commit: objectbox/objectbox-dart@a729705#diff-594a84a4fd72af27284e6f59d689b04f9f1f8cfe9dbcdfb512669d16d0f702b0).

If the maintainers are open to a PR, I could prepare one, though it's going to be a little large, with all those changes in the meantime. Some changes could be cherry-picked but I'd only like to do that if there's a reasonable chance they're going to get merged upstream (i.e. here).

@aardappel I would be happy to do the actual code review of @vaind's PR if you need somebody from the Dart background to do that.

@vaind go ahead, and yes @mraleph that be super helpful!

@vaind how do you handle code-generation with your forked version, or is that not handled yet? Do you have a fork of flatc or no?

I'm trying to figure out if it's possible for me to generate null-safe dart code using flatc with your fork.

[vaind]

@zicklag no, it's currently not supported in flatc - we're using custom code generation specific for objectbox-dart

Waiting for #6661 to be merged, before going ahead with this PR.
