React Navigation re-render previous page when going back

Question

Whats the best way to refresh the previous page when going back using Stack Navigator. No life cycle hooks seems to be triggered on the page i am returning to. I'm just using the basic example and this.props.navigation.goBack()

Answer 1

You can use addListener for this

componentDidMount() {

    this.props.navigation.addListener(
      'didFocus',
      payload => {
        this.forceUpdate();
      }
    );

}
