问题
I'm using material Bottom Tab Navigator, My app is structured such that, some tabs contain a stack navigator. I want to hide the bottom tabs when a user navigates to another stack in the stack navigator. I'm using react navigation v5. I don't want the bottom tabs showing when a user has already navigated to a stack.

I made you a basic example of what you're asking. I hope this what you're looking for :
import React from 'react'
import { Button, View, Text, StyleSheet } from 'react-native'
import { NavigationContainer } from '@react-navigation/native'
import { createMaterialBottomTabNavigator } from '@react-navigation/material-bottom-tabs'
import { createStackNavigator } from '@react-navigation/stack'
const Screen1 = ({ navigation }) => (
<View style={styles.component}>
<Button title="Go to NoBottomComp" onPress={() => navigation.navigate('NoBottomComp')} />
</View>
)
const Screen2 = () => <View style={styles.component}><Text>Screen 2 component</Text></View>
const NoBottomComp = () => <View style={styles.component}><Text>Screen without bottom component</Text></View>
const Footer = createMaterialBottomTabNavigator()
const FooterNav = () => (
<Footer.Navigator>
<Footer.Screen name="Screen1" component={Screen1} />
<Footer.Screen name="Screen2" component={Screen2} />
</Footer.Navigator>
)
const Main = createStackNavigator()
export default props => (
<NavigationContainer>
<Main.Navigator>
<Main.Screen name="BottomNav" component={FooterNav} />
<Main.Screen name="NoBottomComp" component={NoBottomComp} />
{/* As many screens as you want to be without bottom tabs */}
</Main.Navigator>
</NavigationContainer>
)
const styles = StyleSheet.create({
component: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
}
})

I found the answer at this link:
Tab bar can now be hidden #20
What you should do is use the barStyle
attribute with the 'none'
property, which would look like this:
import { createMaterialBottomTabNavigator } from '@react-navigation/material-bottom-tabs'
const BottomTab = createMaterialBottomTabNavigator()
const TabsNavigator = () => (
<BottomTab.Navigator
initialRouteName='Home'
barStyle={{
display: 'none'
}}
>
// Screens
</BottomTab.Navigator>
)
Then you can control that property with a variable, something similar to this:
...
barStyle={{
display: isTabVisible ? null : 'none'
}}
...
However, to control which screens are displayed or not, you can use redux or some way to control the state of the variable isTabVisible
as shown in the following link:
