React navigation 5 hide tab bar from stack navigator

Question

I wanted to know how to hide the bottom tab bar from a specific screen inside my stack navigator that is nested on a material bottom tab bar

This is my code for my stack navigator

import React from 'react';
import { createStackNavigator } from '@react-navigation/stack';
import PondScreen from '../screens/PondScreen/PondScreen';
import PondDetailScreen from '../screens/PondScreen/PondDetailScreen';

const Stack = createStackNavigator();

export function PondStack() {
  return (
    <Stack.Navigator
      initialRouteName="PondScreen"
      headerMode="none"
      mode="card"
    >
      <Stack.Screen
        name="PondScreen"
        component={PondScreen}
      />
      <Stack.Screen
        name="PondDetailScreen"
        component={PondDetailScreen}
        options={{
          tabBarVisible: false
        }}
      />
    </Stack.Navigator>
  );
}

This is my code for my material bottom tab navigator

import React from 'react';
import { View } from 'react-native';
import { createMaterialBottomTabNavigator } from '@react-navigation/material-bottom-tabs';
import { Entypo, Feather } from '@expo/vector-icons';
import { PondStack } from './StackNavigators';
import StockScreen from '../screens/StockScreen';
import OrderScreen from '../screens/OrderScreen';
import SettingsScreen from '../screens/SettingsScreen';

const Tab = createMaterialBottomTabNavigator();

export default function BottomTab() {
  return (
    <Tab.Navigator
      labeled={false}
      initialRouteName="Pond"
      activeColor="#EB3349"
      inactiveColor="#888888"
      backBehavior="none"
      shifting={true}
      barStyle={{
        backgroundColor: '#FFFFFF'
      }}
    >
      <Tab.Screen
        name="Pond"
        component={PondStack}
        options={{
          tabBarIcon: ({ color}) => (
            <View style={{ flex: 1 }}>
              <Entypo name="air" color={color} size={20} />
            </View>
          )
        }}
      />
      <Tab.Screen
        name="Stock"
        component={StockScreen}
        options={{
          tabBarIcon: ({ color }) => (
            <View style={{ flex: 1 }}>
              <Feather name="box" color={color} size={20} />
            </View>
          )
        }}
      />
      <Tab.Screen
        name="Order"
        component={OrderScreen}
        options={{
          tabBarIcon: ({ color}) => (
            <View style={{ flex: 1 }}>
              <Feather name="dollar-sign" color={color} size={20} />
            </View>
          )
        }}
      />
      <Tab.Screen
        name="Settings"
        component={SettingsScreen}
        options={{
          tabBarIcon: ({ color}) => (
            <View style={{ flex: 1 }}>
              <Feather name="settings" color={color} size={20} />
            </View>
          )
        }}
      />
    </Tab.Navigator>
  )
}

Answer 1

I had almost the same issue with a tabnavigation as parent and stacknavigation as childs and rearranging my screen layer wasn't an option. So I looked for another solution and from the docs I found out that the parent navigation UI is always shown on the child. But the docs also gave a great example on how to change a parent header from within a child. So I took that example and implemented it for the tabbar visibility. This is how I implemented it.

So I have a tabbar navigation with Home, Contacts and More, and inside each tab I have a stack. The screen that I hide the tabbar in is in the CameraView, and that screen is a stackscreen in the More tab.

• Home
• Contacts
• More

  • Profile
  • CameraView (here I want to hide the tabbar)

Tabnavigation:

As you can see I get the visibility of the tabbar from a method.

<NavigationContainer>
  <Tab.Navigator>
    <Tab.Screen name="Home" component={HomeNavigation} />
    <Tab.Screen name="Contacts" component={ContactNavigation} />
    <Tab.Screen
      name="More"
      component={MoreNavigation}
      options={({ route }) => ({
        tabBarVisible: this.getTabBarVisibility(route)
      })}
    />
  </Tab.Navigator>
</NavigationContainer>

Method getTabBarVisibility:

This is were I check if the name of the route is CameraView which I defined in the StackNavigation.

getTabBarVisibility = (route) => {
  const routeName = route.state
    ? route.state.routes[route.state.index].name
    : '';

  if (routeName === 'CameraView') {
    return false;
  }

  return true;
}

And the component MoreNavigation:

This is my stacknavigation for More, where you can see that the screen name is CameraView.

<Stack.Navigator initialRouteName="More">
  <Stack.Screen name="More" component={More}/>
  <Stack.Screen name="UserProfile" component={Profile}/>
  <Stack.Screen name="CameraView" component={CameraView}/>
</Stack.Navigator>
