Use case

Dependencies do not resolve when trying to use a version of analyzer greater than 9.0.0

Proposed solution

Address deprecations / breaking changes and update the constraints for analyzer in objectbox_generator

Additional context

[package:example] flutter pub get --no-example
Resolving dependencies...
Because objectbox_generator 5.1.0 depends on analyzer ^8.1.1 and no versions of objectbox_generator match >5.1.0 <6.0.0, objectbox_generator ^5.1.0 requires analyzer ^8.1.1.
So, because example depends on both analyzer ^10.0.1 and objectbox_generator ^5.1.0, version solving failed.


You can try the following suggestion to make the pubspec resolve:
* Consider downgrading your constraint on analyzer: flutter pub add analyzer:^8.4.1
