Does not generate .g.dart files any more

[HosseinArabbeigi]

here is my classes and my user model that generated just one time, but it doesn't generate change after running build command and if i delete last user.g.dart it will not regenerate.

i have this warning some times:

Try replaying the full URI for the part file with just

part 'user.g.dart';".
