Extending generic class leads to error

[ValeriusGC]

Hello. I changed sample in extend_serializables to generic to emulate my real case Derived => Base<T>

@serializable
class Person<T> extends _$PersonSerializable<T> {
  int id;
  T firstName;
  String lastName;
  DateTime dateOfBirth;
}

@serializable
// ignore: mixin_inherits_from_not_object
class Employee extends Person<String> with _$EmployeeSerializable {
  double salary;
}

and got an issue:

[SEVERE] dson|dson_builder on example/bin/extend_serializables.dart:
Error formatting generated source code for 102dson/example/bin/extend_serializables.dartwhich was output to example/bin/extend_serializables.g.dart.
This may indicate an issue in the generated code or in the formatter.
Please check the generated code and file an issue on source_gen if appropriate.
Could not format because the source could not be parsed:

fixed, please upgrade version of built_mirrors to 0.10.3, maybe you only need to run pub upgrade

[ValeriusGC]

What do you exactly mean? First there is no such built_mirrors 0.10.3 version in pub repository. Second there is no points in DSON documentation about adding this dependency in YAML. So what shall I do?

[luisvt]

ups sorry, my mistake it should be built_mirrors_core.

Don't worry about it, just run pub upgrade or specify the version of dson to version ^0.15.4
