Is it possible to scroll to component after the component shown?

[ivanasetiawan]

I need to scroll to the component after it gets rendered to the page. The component itself is not shown bu default (the component will be rendered when example_shown is true). Something like this:
{props.example_shown && ( <ExtraComponent /> )}

and inside the ExtraComponent, I give ref={(section) => { this.ExtraComponent = section }}.
I tried to call scrollToComponent inside componentDidMount() but this.ExtraComponent returns to null. How can I scroll to position

add dummy elements containing no children but visible as anchor hooks

{ this.ExtraComponent = section }}>

{props.example_shown && ( )}
