How to navigate between different nested stacks in react navigation

In React Navigation 5, this becomes much easier by passing in the screen as the second parameter:

navigation.navigate('Nested Navigator 2', { screen: 'screen D' });

You can also include additional levels if you have deeply nested screens:

navigation.navigate('Nested Navigator 2', {
    screen: 'Nested Navigator 3', params: {
        screen: 'screen E'
    }
});
