How do I pass initial props (or launchoptions) to first scene?

Question

I am sending data from Android Native to React native by setting a simple prop in Android via the launchoptions.

I was successfully able to receive the initial props in the react-native module, but now when I am using StackNavigator like this :

const RootStack = createStackNavigator(
    { 
        home: Details,
        genre: Genre,
    },
    { 
        initialRouteName: 'home',
    }
);
const AwesomeProject = createAppContainer(RootStack);
export default AwesomeProject;

Now I am unable to use my Prop in the HomeScreen's constructor. How do I pass my initial props into the home screen?

The react-native version I am using is 0.58.4

Here's the full Code in React-Native :

import { 
  createStackNavigator, 
  createAppContainer 
} from 'react-navigation';

import Genre from './app/Genre';
import Details from './app/Details';

const RootStack = createStackNavigator(
    { 
        home: Details,
        genre: Genre,
    },
    { 
        initialRouteName: 'home',
    }
);

const AwesomeProject = createAppContainer(RootStack);
export default AwesomeProject;

Here's the Android code:

@Override
    protected ReactActivityDelegate createReactActivityDelegate() {
        return new ReactActivityDelegate(this, getMainComponentName()) {
            @Nullable
            @Override
            protected Bundle getLaunchOptions() {
                Bundle bundle = new Bundle();
                String str = MainActivity.getMovieID();
                bundle.putString("movie_id", str);
                return bundle;
            }
        };
    }

My problem is exactly same as this one: https://github.com/react-navigation/react-navigation/issues/634

But the problem is the solution given by the user is for an older version of react and in the new react-navigation-3 you must set up your app container directly, so his solution does not work.

Please help.

Finally got it to work and was successfully able to send initialProps from native android to react-native's first scene of StackNavigator like this:

const StackNavigator = createStackNavigator(
    { 
        home:  {screen: Details},
        genre: {screen: Genre},
    },
    { 
        initialRouteName: 'home',
    }
);

const RootStack = createAppContainer(StackNavigator)

export default class AwesomeProject extends Component {
    constructor(props){
        super(props)
    }

    render() {
    return <RootStack screenProps={this.props.movie_id} />;
  }
}
