如何扩展angular @input装饰器？

Question

我正在尝试编写自定义属性装饰器，以扩展@Input装饰器的角度。

我的目标是使用现有的属性选择器获取Localizable属性。

./ decorators / my-decorators.ts

import {Input} from '@angular/core';
export interface InputDefinition {localizable: boolean; selector: string; }
export function MyInput(inputDefinition: InputDefinition) {
    const ngInput = Input(inputDefinition.selector);
    return function (target: any, key: string) {
        if (inputDefinition.localizable === true) {
            console.log(`loclizable input ${inputDefinition.selector}`);
            // implement localization for property.
        }
      ngInput(target, key);
    };
}

./ my-component / mycomponent.ts

import { Component, Input } from '@angular/core';
import { MyInput } from '../decorators/my-decorators';

@Component({
  selector: 'my-component',
  template: `<h1>{{myInput}}</h1>`
})
export class MyComponent {
  //define input property with custom decorator 
  @MyInput({selector: 'my-input', localizable: false})
  myInput = 'input default value';
}

./ app.component.html

<div style="text-align:center">
  <my-component my-input="bound value"></my-component>
</div>

ng serve

似乎工作得很好，但是当我在产品模式下运行它时。.

--ng serve --prod

没有任何构建错误或运行时错误，但是属性绑定在产品构建中不起作用。

各种建议都会有所帮助。

提前感谢
