flutter / dart 可反射包：不反射 base/super class 成员

Question

import 'package:reflection_test2/common/reflect/Reflector.dart';

@reflector
class Base
{
  String s1;
}

@reflector
class Sub extends Base
{
  String s2;
}

ClassMirror classMirror = reflector.reflectType(Sub);

=>这里class镜像只反射s2，不反射base/super class成员s1.

Answer 1

不确定您需要对 s1 字段做什么，但下面列出了一种访问它的方法。 希望对你有帮助。

class Reflector extends Reflectable {
  // config reflect capabilities
  const Reflector() : super(invokingCapability, declarationsCapability, typeRelationsCapability);
}

ClassMirror classMirror = reflector.reflectType(Sub);
// print all instance members of the superclass (e.g. toString, s1, etc.)
classMirror.superclass.instanceMembers.forEach((key, value) => print(value.simpleName));
