    Because freezed >=2.2.0 <3.0.0-0.0.dev depends on build ^2.3.1 and freezed >=1.0.1 <2.2.0 depends on source_gen ^1.2.0, freezed >=1.0.1 <3.0.0-0.0.dev requires build ^2.3.1 or source_gen ^1.2.0.
(1) So, because json_serializable >=6.13.1 depends on both build ^4.0.4 and source_gen ^4.1.2, freezed >=1.0.1 <3.0.0-0.0.dev is incompatible with json_serializable >=6.13.1.

Run flutter pub downgrade and then flutter analyze to reproduce the above problem.

You may run dart pub upgrade --tighten to update your dependency constraints, see dart.dev/go/downgrade-testing for details.
