Dart 反射 获取一个类所有属性和方法

import 'dart:mirrors';

class Test {
    int a = 5;

    static int s = 5;

    final int _b = 6;

    int get b => _b;

    int get c => 0;
}

void main() {

    Test t = new Test();
    InstanceMirror instance_mirror = reflect(t);
    var class_mirror = instance_mirror.type;

    for (var v in class_mirror.declarations.values) {

        var name = MirrorSystem.getName(v.simpleName);

        if (v is VariableMirror) {
            print("Variable: $name => S: ${v.isStatic}, P: ${v.isPrivate}, F: ${v.isFinal}, C: ${v.isConst}");
        } else if (v is MethodMirror) {
            print("Method: $name => S: ${v.isStatic}, P: ${v.isPrivate}, A: ${v.isAbstract}");
        }

    }
