ReactiveColorPicker : Use integer instead of Color for value(s)

[Dionnie]

I use reactive_forms_generator and freezed for generating form models and I noticed that using Color type which is different from int,double,String introduces more complexity & errors by the time you want to save the color on database.

Luckily in dart, we can create Color using an integer e.g

int foo = 0xFFFFA500;
Color(foo); // Result: Yellow
Color(foo).value //Result: 0xFFFFA500

ReactiveColorPicker should accept an integer instead of Color? I think?
Thank you.
