In Dart we add methods like toJson() and Model.fromJson() inside model, does this breaks MVVM or SOLID principles?
CodePudding user response：
No, it doesn't, it's totally the opposite, it's recommended to set model JSON converters factories and methods of a model inside its implementation.
check this:
the goal of those methods is to handle serializing your model, to make your life easier when working with APIs, and external data...
I would say that what's not a good practice, is to try to handle JSON serialization inside your business logic.
