@Entry
@Component
struct MyComponent {
  onPageHide() {
    console.info('Page is hiding');
  }

  aboutToDisappear() {
    console.info('MyComponent will disappear');
  }

  build() {
    Column() {
      Button('Push to next page').onClick(() => router.replaceUrl('pages/Page2'));
    }
  }
}

@Component
struct ChildComponent {
  aboutToDisappear() {
