How can I navigate to a specific screen when navigation stack is empty?

Issue

How can I do this:

if navigation stack is not empty
    this.props.navigation.goBack()
else
    this.props.navigation.navigate('CustomScreen')

Solution

a workaround solution is sending param from previous screen and in current screen check if that param exist

Screen1:

this.props.navigation.navigate('Screen2', {prevScreen: 'Screen1'});

Screen2:

if(this.props.navigation.getParam('prevScreen', null))
    this.props.navigation.goBack();
else
    this.props.navigation.navigate('CustomScreen');
