将类变量转换为dart中的映射

import 'dart:mirrors';

class MyClass {
  int id;
  String name;

  MyClass(this.id, this.name);
}

Map<String, dynamic> classToMap(Object obj) {
  Map<String, dynamic> map = {};
  InstanceMirror instanceMirror = reflect(obj);
  ClassMirror classMirror = instanceMirror.type;

  classMirror.declarations.forEach((symbol, declaration) {
    if (declaration is VariableMirror && !declaration.isPrivate) {
      String fieldName = MirrorSystem.getName(symbol);
      InstanceMirror fieldMirror = instanceMirror.getField(symbol);
      dynamic fieldValue = fieldMirror.reflectee;
      map[fieldName] = fieldValue;
    }
  });

  return map;
}

void main() {
  MyClass myObj = MyClass(1, 'John');
  Map<String, dynamic> myMap = classToMap(myObj);
  print(myMap);
}
