如何显示使用OnPush变更检测的加载模板？

@Component({
  selector: 'app-my-component',
  templateUrl: './my-component.component.html',
  changeDetection: ChangeDetectionStrategy.OnPush
})

<ng-container *ngIf="condition">
  <!-- 加载模板内容 -->
</ng-container>

import { Component, OnInit, ChangeDetectionStrategy, ChangeDetectorRef } from '@angular/core';

@Component({
  selector: 'app-my-component',
  templateUrl: './my-component.component.html',
  changeDetection: ChangeDetectionStrategy.OnPush
})
export class MyComponent implements OnInit {
  condition: boolean = false;

  constructor(private cdr: ChangeDetectorRef) { }

  ngOnInit(): void {
    // 在需要的时候更新视图
    this.cdr.markForCheck();
  }
}
