AfterContentChecked

A lifecycle hook that is called after the default change detector has completed checking all content of a directive. It will run after the content has been checked and most of the time it's during a change detection cycle.

      
      interface AfterContentChecked {
ngAfterContentChecked(): void }

Usage notes

The following snippet shows how a component can implement this interface to define its own after-check functionality.

      
      @Component({selector: 'my-cmp', template: `...`})
class MyComponent implements AfterContentChecked {
  ngAfterContentChecked() {
    // ...
  }
}
