mobx_codegen: ^1.0.3 与 json_model: ^0.0.2存在 build_runner版本冲突

[593980284]

And because mobx_codegen >=0.1.3 depends on build ^1.1.4 and mobx_codegen >=0.4.2 depends on build_resolvers ^1.3.2, mobx_codegen >=0.4.2 requires build ^1.2.0. And because json_model 0.0.2 depends on build >=1.0.0 <1.2.0 and no versions of json_model match >0.0.2 <0.1.0, mobx_codegen >=0.4.2 is incompatible with json_model ^0.0.2. So, because network depends on both json_model ^0.0.2 and mobx_codegen ^1.0.3, version solving failed. pub get failed (1; So, because network depends on both json_model ^0.0.2 and mobx_codegen ^1.0.3, version solving failed.) exit code 1
