Is it right way to using freezed?

[Raonshi]

Hello, I'm developing a large project using flutter with freezed.

Currently, I'm using freezed as "Data model generator". But, I felt I'm using freezed wrong way sometimes.

For example, In my project, There are so many ResponseModel classes to receive json data from server. Some models has many subtype as Union class.

When generate these classes using build_runner, It takes too much time and generate too many code lines (almost 160000 lines).So, I tried disable some options using @freezed() annotation, but freezed generated almost 12000 lines.

I know I'm using freezed as wrong way. But I don't know how can I resolve this confusing things.

Separating big data model file to small files is right way? Or there are another ways?

Thank you for reading this Question.
