flutter_lints dependency

[cekrozl1]

Hi !

When trying to update the flutter_lints dev dependency from 3.0.2 to 4.0.0, I get this error:

Because flutter_json_view 1.1.4 depends on flutter_lints >=2.0.0 <4.0.0 and no versions of flutter_json_view match >1.1.4 <2.0.0, flutter_json_view ^1.1.4 requires flutter_lints >=2.0.0 <4.0.0.
So, because third_generation depends on both flutter_json_view ^1.1.4 and flutter_lints ^4.0.0, version solving failed.

I think it should be easy to fix. Thanks !
