希望更新 json_serializable 依赖

[TangJinJian]

Because every version of json_model depends on json_serializable ^2.0.0 and flutter_todo depends on json_serializable ^3.2.5, json_model is forbidden.

So, because flutter_todo depends on json_model ^0.0.2, version solving failed. pub get failed (1; So, because flutter_todo depends on json_model ^0.0.2, version solving failed.)

I am also getting the error. I think upgrading to flutter_dev solves the issue, but for me, upgrading causes other problems
