React Native Open Drawer with Button - react-native

Question

I have a Drawer Navigator with some Screens. One of the Screens is a TabNavigator. Now I want to implement a HamburgerMenu-Button to open the drawer in all of the Tab-Navigator Screens.
Where do I implement that Button? In the TabNavigator or its child Screens or in the Drawer Screens?
Here are a few Code Snippets:
DrawerNavigator:
export default class DrawerMenu extends React.Component {
render() {
return (
<Drawer.Navigator initialRouteName='Home'>
<Drawer.Screen name='Home' component={TabNavigator} />
<Drawer.Screen name='About Us' component={AboutUsScreen} />
<Drawer.Screen name='About the App' component={AboutTheAppScreen} />
<Drawer.Screen name='Impressum' component={ImpressumScreen} />
</Drawer.Navigator>
);
}
}
TabNavigator:
const Tab = createBottomTabNavigator();
const TabNavigator = () => {
return (
<Tab.Navigator tabBar={(props) => <TabBar {...props}></TabBar>}>
<Tab.Screen
name='Tab1'
component={Tab1}
initialParams={{ icon: 'info' }}
></Tab.Screen>
<Tab.Screen
name='Tab2'
component={Tab2}
initialParams={{ icon: 'circle-o-notch' }}
></Tab.Screen>
<Tab.Screen
name='Tab3'
component={Tab3}
initialParams={{ icon: 'home' }}
></Tab.Screen>
<Tab.Screen
name='Tab4'
component={Tab4}
initialParams={{ icon: 'glass' }}
></Tab.Screen>
<Tab.Screen
name='Tab5'
component={Tab5}
initialParams={{ icon: 'road' }}
></Tab.Screen>
</Tab.Navigator>
);
};
single Screen in TabNavigator:
const Tab1 = () => {
return (
<View style={styles.container}>
<Text style={styles.text}>Tab1</Text>
</View>
);
};
Any help is appreciated.

Answer 1

In the end it was an easy answer. We just had to give through the props. (I think)
single Screen in TabNavigator:
const Tab1 = ({navigation}) => {
return (
<View style={styles.container}>
<Text style={styles.text}>Tab1</Text>
</View>
);
};
That way we could easily use the navigation.openDrawer function in an onPress event.
