如何在angular 8中将事件从一个父组件获取到子组件？

// 父组件
import { Component } from '@angular/core';

@Component({
  selector: 'app-parent',
  template: `
    <button (click)="handleClick()">点击我</button>
    <app-child [parentClick]="clicked"></app-child>
  `
})
export class ParentComponent {
  clicked = false;

  handleClick() {
    this.clicked = true;
  }
}

// 子组件
import { Component, Input } from '@angular/core';

@Component({
  selector: 'app-child',
  template: `
    <div *ngIf="parentClick">父组件的点击事件已触发</div>
  `
})
export class ChildComponent {
  @Input() parentClick: boolean;
}
