Class can't be used as mixin because it declares constructor...

[ValeriusGC]

in your sample:

@FunctionalData()
class Foo with $Foo {
  final int number;
  final String name;

  // Can't be const because of mixin
  Foo({this.number, this.name});
}

in real life i got error Class can't be used as mixin because it declares constructor...

@immutable
@FunctionalData()
class Base with $Base{
  final int uid;
  final int editTime;

  Base({this.uid, this.editTime});
}

So, how one can use this with inheritance?

Looks like a mistake in the documentation (or a left-over from an earlier incarnation). Instead: class Base extends $Base should work.

I've fixed the documentation.

So, is it planning to use this with inheritance?

@spkersten Can the generated class to be a mixin? As dart not support multiple inheritance.
