问题
I am trying to hide the ability to press one of my routes in the drawer navigator as it is another navigator and the default location in the app. I want the drawer to simply be used for navigating to extraneous routes that don't fit well into user flow elsewhere. Before React Navigation 5 I was able to achieve this by simply setting drawerLabel: () => null. However now with the changes I cannot figure out how to hide this in the same manner.
Below is my current navigator code:
const DrawerNavigator = () => {
const dispatch = useDispatch();
return (
<MainDrawerNavigator.Navigator
drawerContent={props => customDrawerContent(props, dispatch)}
drawerStyle={drawerStyle}
>
<MainDrawerNavigator.Screen
name="DrawerNav"
component={MainTabNavigator}
options={{
drawerLabel: () => null,
title: null,
drawerIcon: () => null
}}
/>
<MainDrawerNavigator.Screen
name="FAQNav"
component={FAQStackNavigator}
options={
{
drawerLabel: "FAQ",
drawerIcon: ({tintColor}) => <EvilIcons name={'question'} size={30} color={tintColor} />
}
}
/>
</MainDrawerNavigator.Navigator>
)
}
const customDrawerContent = (props, dispatch) => {
console.log(props.descriptors)
return (
<View style={{flex: 1}}>
<View style={{height: '90%'}}>
<DrawerContentScrollView {...props}>
<View style={styles.logoContainer}>
<Image
style={styles.image}
fadeDuration={0}
resizeMode={'contain'}
source={require('../assets/images/spikeball-logo-horizontal.png')}
/>
</View>
<TouchableOpacity style={styles.contactUsContainer} onPress={() => { Linking.openURL('https://spikeball.com/')}}>
<AntDesign style={styles.iconStyle} name={'shoppingcart'} size={25} color={'black'} />
<Text style={styles.drawerText}>Shop</Text>
</TouchableOpacity>
<TouchableOpacity style={styles.contactUsContainer} onPress={() => { Linking.openURL('https://support.spikeball.com/')}}>
<AntDesign style={styles.iconStyle} name={'contacts'} size={25} color={'black'} />
<Text style={styles.drawerText}>Contact Us</Text>
</TouchableOpacity>
<DrawerItemList
{...props}
/>
</DrawerContentScrollView>
</View>
<TouchableOpacity
style={styles.logoutContainer}
onPress={() => {
dispatch(authActions.logout());
}}>
<Text style={styles.logoutText}>SIGN OUT</Text>
</TouchableOpacity>
</View>
)
}
Link to image showing the undesired output. Basically I want the blue focus and entire nav item hidden from the naw bar specifically. UNDESIRED Output

Best solution will be filter the props before pass it to DrawerItemList . This will only work react navigation 5
//custom drawer content
export default props => {
const { state, ...rest } = props;
const newState = { ...state} //copy from state before applying any filter. do not change original state
newState.routes = newState.routes.filter(item => item.name !== 'Login') //replace "Login' with your route name
return (
<DrawerContentScrollView {...props}>
<DrawerItemList state={newState} {...rest} />
</DrawerContentScrollView>
)
}

Solved the issue with the following
import React from 'react';
import { SafeAreaView, View, Text, StyleSheet, Image, Linking } from 'react-native';
import { EvilIcons, AntDesign } from '@expo/vector-icons';
import { useDispatch } from 'react-redux';
import { createDrawerNavigator, DrawerContentScrollView, DrawerItemList, DrawerItem } from '@react-navigation/drawer';

const MainDrawerNavigator = createDrawerNavigator();
const DrawerNavigator = () => {
const dispatch = useDispatch();
return (
<MainDrawerNavigator.Navigator
drawerContent={props => customDrawerContent(props, dispatch)}
drawerStyle={drawerStyle}

<MainDrawerNavigator.Screen
name="DrawerNav"
component={MainTabNavigator}
options={{

{/* Tried just disabling using DrawerItemList but wasn't working so made
complete custom drawer component and navigate properly using props.navigation.navigate */}

export default DrawerNavigator;

For me you would better creating a nested navigator with stack and drawer screens as documented in https://reactnavigation.org/docs/nesting-navigators/#navigator-specific-methods-are-available-in-the-navigators-nested-inside instead of hiding drawer item.

Solution for React Navigation 5
I ended up using the following code -
drawerContent={props => customDrawerContent(props, dispatch)}
Code of customDrawerContent -
{state.routes.map((route, i) => {
if(route.name === 'App') return;
const focused = i === state.index;
const { title, drawerLabel, drawerIcon } = descriptors[route.key].options;
return (
<DrawerItem
key={route.key}
label={
drawerLabel !== undefined
? drawerLabel
: title !== undefined
? title
: route.name
}
icon={drawerIcon}
focused={focused}
activeTintColor={activeTintColor}
inactiveTintColor={inactiveTintColor}
activeBackgroundColor={activeBackgroundColor}
inactiveBackgroundColor={inactiveBackgroundColor}
labelStyle={labelStyle}
style={itemStyle}
to={buildLink(route.name, route.params)}
onPress={() => {
navigation.dispatch({
...(focused
? DrawerActions.closeDrawer()
: CommonActions.navigate(route.name)),
target: state.key,
});
}}
/>
);
})}
