Dependency conflict: hive_generator ^2.0.1 incompatible with json_serializable ^6.9.2

There is a dependency conflict when using hive_generator version ^2.0.1 alongside json_serializable version ^6.9.2 due to differing source_gen version requirements:

Because hive_generator 2.0.1 depends on source_gen ^1.0.0 and json_serializable 6.9.2 depends on source_gen ^2.0.0, json_serializable ^6.9.2 is incompatible with hive_generator ^2.0.1.
So, because smart_by_jarod depends on both hive_generator ^2.0.1 and json_serializable ^6.9.2, version solving failed.

Environment:
• Flutter version: 3.27.1 (stable)
• Dart version: 3.6.0
• OS: macOS 15.2 (darwin-arm64)

Reproduce the pub version-solving failure in a minimal Dart/Flutter setup using hive_generator ^2.0.1 and json_serializable ^6.9.2; inspect the packages' source_gen constraints first. Done means the two dependencies resolve together under the reported Dart and Flutter versions, with code generation still working.
