React Native: React Navigation - use the same header component in every screen? - react-native

Question

So, I'm trying to use React Navigation and I want to use the same Header component across all my screens.
I used the expo-cli to create the project.
In my MainTabNavigator.js file, I have a HomeStack and SettingsStack, and they look like this:
const config = Platform.select({
web: { headerMode: "screen" },
default: {}
});
const HomeStack = createStackNavigator(
{
Home: HomeScreen
},
config
);
HomeStack.navigationOptions = {
tabBarIcon: ({ focused }) => (
<NavButton
focused={focused}
name={focused ? "star" : "create"}
label={focused ? "Save" : "New"}
/>
)
};
HomeStack.path = "";
At the bottom of the file, I have my tabNavigator
const tabNavigator = createBottomTabNavigator(
{
HomeStack,
SettingsStack
},
{
tabBarOptions: {
inactiveTintColor: "#fff",
labelStyle: {
fontSize: 14
},
showLabel: false,
style: {
backgroundColor: "#fff",
borderTopColor: "#fff",
height: 70,
paddingBottom: 10,
paddingTop: 10
}
}
}
);
tabNavigator.path = "";
export default tabNavigator;
I tried adding a <Header /> component in the navigatorOptions and defaultNavigationOption above the tabBarOptions in the createBottomTabNavigator function.
Similar to this:
...
{
navigationOptions: {
header: <Header />
},
tabBarOptions: {
inactiveTintColor: "#fff",
labelStyle: {
fontSize: 14
},
...
but this just gives me a blank header... not using my component.
I currently have the functionality I want, but I have to go into each Screen file and add:
HomeScreen.navigationOptions = {
header: <Header />
};
Currently using "react-navigation": "^3.11.0"
Any help is appreciated!

This is how I'm achieving this.
Create a CustomHeader component like this:
const MyHeader = (navigation) => {
return {
header: props => <MyCustomHeader {...props} />,
headerStyle: { backgroundColor: '#fff' },
headerTintColor: '#000',
};
}
Then include it in defaultNavigationOptions in your stack navigator
const AppNavigator = createStackNavigator(
{
Launch: {
screen: LaunchComponent,
}
},
{
initialRouteName: "Launch",
defaultNavigationOptions: ({ navigation }) => {
return MyHeader(navigation)
}
}
)

I wanted to achieve similar solution for DrawerNavigator. The only way to do this was to create HOC component.
import React, {Fragment} from 'react';
const NavHeader = props => {
// ... NavHeader code goes here
};
export const withHeader = Component => {
return props => {
return (
<Fragment>
<NavHeader {...props} />
<Component {...props} />
</Fragment>
);
};
};
Then in your Drawer you do:
<Drawer.Navigator>
<Drawer.Screen
name={ROUTES.DASHBOARD}
component={withHeader(DashboardContainer)} // <--- Wrap it around component here.
/>
</Drawer.Navigator>

Set your StackNavigator as parent of your BottomTabNavigator, doing it will let you have a single header for all the bottomTabs.
If you use this approach, and need for some reason to have a backButton on your header you have to change it manually yourself.
const bottomTabNavigator = createBottomTabNavigator(bottomRoutesConfig, bottomNavigatorConfigs)
createStackNavigator:({ tabNavigator : bottomTabNavigator },{ defaultNavigationOptions :{ header : <Header/> }})
Doing this you can use one global header for all the screens, but as said, to change something on the header based off the screen you have to change it yourself, making the header know in what location the user currently is.

set header to null in every screen and load your component on each screens
class HomeScreen extends Component {
static navigationOptions = {
header: null,
};
render(){
return(
<View style={{flex:1}}>
<Header />
</View>
)
}
}
so, the default header of react-navigation will be null and you can load your custom component as header
OR
class HomeScreen extends React.Component {
static navigationOptions = {
// headerTitle instead of title
headerTitle: <Header />,
};
/* render function, etc */
}
use headerTitle instead of title to load your custom component
