如何在ionic中添加工厂？

import { Injectable } from '@angular/core';

@Injectable()
export class MyFactory {
  createObject(param: any): any {
    // 根据参数创建对象
    // 返回所需的对象实例
  }
}

import { Component } from '@angular/core';
import { MyFactory } from '../path/to/factory';

@Component({
  selector: 'app-my-component',
  templateUrl: './my-component.html',
  styleUrls: ['./my-component.scss'],
})
export class MyComponent {
  constructor(private myFactory: MyFactory) {
    // 在构造函数中注入工厂类的实例
  }

  createObject(param: any): void {
    const obj = this.myFactory.createObject(param);
    // 使用工厂创建对象
  }
}
