Support source_gen 2 and analyzer 7

[Shajk0]

Hey guys

I wanted to test objectbox, but I get a dependency error.
Seems like a too old version of source_gen is used and so I have a conflict with other packges.
Could you please update this to source_gen to version 2.0.0

Because no versions of objectbox_generator match >4.0.3 <5.0.0 and objectbox_generator 4.0.3 depends on source_gen ^1.0.0, objectbox_generator ^4.0.3 requires source_gen ^1.0.0.

Edit:
Found another conflict:
Because no versions of objectbox_generator match >4.0.3 <5.0.0 and objectbox_generator 4.0.3 depends on analyzer >=5.2.0 <7.0.0, objectbox_generator ^4.0.3 requires analyzer >=5.2.0 <7.0.0. And because riverpod_lint >=2.6.4 <3.0.0-dev.0 depends on analyzer ^7.0.0, objectbox_generator ^4.0.3 is incompatible with riverpod_lint >=2.6.4 <3.0.0-dev.0.

Thanks for reporting! We will test with the newer versions, make required changes and then allow them in pubspec.

As for the first message the relevant part is missing ("is incompatible with...") so I can't advice. But the solution is the same as for the second conflict:

To avoid compatibility issues, add packages using the pub add command. For example for ObjectBox:

dart pub add objectbox
dart pub add --dev build_runner objectbox_generator:any

The same applies for updates, use the pub upgrade command instead of editing versions by hand.

You can also manually change your pubspec to allow the needed versions of the conflicting dependency, like for riverpod_lint allow lower than version 2.6.4. Then Flutter (or rather pub) will find versions that work together for you.

Edit: there is a chance that finding matching versions is impossible. In this case a dependency override to force a specific version can be a temporary solution. However, building may fail if APIs of that package that are used in other packages have changed.

For our reference, this is internal issue objectbox-dart#133.

I have the same issue when I try to used the actual version of freezed: (2.5.8)

And because objectbox_generator >=0.13.0+1 depends on source_gen ^1.0.0 and freezed >=2.5.8 <3.0.0-0.0.dev depends on source_gen ^2.0.0,
  freezed >=2.5.8 <3.0.0-0.0.dev is incompatible with objectbox_generator.

@simeonApproppo If you are saying my recommendation to allow more versions does not work, I updated my comment above to include a workaround for that case.

[simeonApproppo]

Downgrading to freezed 2.5.7 is working.. But I hope that you will release a version, that depends on a actual version of source_gen soon. :-)

@greenrobot-team Using dependency overrides won't work as source_gen 3.0.0 introduces breaking changes (https://pub.dev/packages/source_gen/changelog).

[greenrobot-team]

@mike-500 Thanks for the info! It also requires at least Dart 3.6. As we try to support as many old Dart (and Flutter) versions as possible, that is another thing to consider.

But as the first comment already has 6 thumbs ups I guess doing it soon is more important.

Hello, objectbox cannot be used with latest versions of auto_route and not compatible with json_serializable:

Because objectbox_generator <0.13.0-nullsafety.0 doesn't support null safety and objectbox_generator >=0.13.0-nullsafety.0 <0.13.0+1 depends on source_gen ^0.9.0, objectbox_generator <0.13.0+1 requires source_gen ^0.9.0.
And because objectbox_generator >=0.13.0+1 depends on source_gen ^1.0.0, every version of objectbox_generator requires source_gen ^0.9.0 or ^1.0.0.
And because json_serializable 6.9.4 depends on source_gen ^2.0.0 and no versions of json_serializable match >6.9.4 <7.0.0, objectbox_generator is incompatible with json_serializable ^6.9.4.
So, because glue_app depends on both json_serializable ^6.9.4 and objectbox_generator any, version solving failed.

Overriding source_gen to ^2.0.0 leads to issue with dart_style used by auto_route_generator

@azlekov AutoRoute downgrade to 9.0.0 works for me, and it's still the same major version. Didn't check the json_serializable though.

I really don't want to downgrade my packages, any progress with this issue?
