Completion block for dismiss light box

Question

Is there way to execute the code right after lightBox has been dismissed? I am looking for an equivalent of completion block:

Navigator.dismissLightBox();
//wait for it to dismiss and execute code

Answer 1

You can pass a callback in passProps and invoke that callback in componentwillunmount

Navigation.showLightBox({
  screen: "example.LightBoxScreen",
  passProps: {
    onDismiss: () => console.log('dismissed')
  }
});
