I'm fairly new to React native . I have created a Drawer Navigator in my App.js file.
One of my navigation Components is a component named LoginScreen.
I am trying to to pass a prop to LoginScreen to display when the user navigates to it.
App.js (Navigator)
const Tab = createMaterialBottomTabNavigator()
const Stack = createStackNavigator()
const Drawer = createDrawerNavigator()
export default class App extends Component {
constructor(props) {
super(props)
this.state = {
isAdmin: 'false',
checked: false,
}
}
async componentDidMount() {
try {
const adm = await AsyncStorage.getItem('is_admin')
if (adm == null) {
adm = await AsyncStorage.setItem('is_admin', 'false')
}
this.setState({ isAdmin: adm, checked: true })
} catch (error) {
console.log(error)
}
}
render() {
const { isAdmin } = this.state
console.log(isAdmin)
//is admin
return isAdmin == 'true' ? (
<NavigationContainer>
<Drawer.Navigator initialRouteName="Home">
<Drawer.Screen name="Home" component={MyStack} />
<Drawer.Screen
name="Admin Panel"
component={props => {
return <LoginScreen props={props} propName = {'Hello'} />
}}
/>
</Drawer.Navigator>
</NavigationContainer>
) : (
//ISNOT ADMIN
<NavigationContainer>
<Drawer.Navigator initialRouteName="Home">
<Drawer.Screen name="Home" component={MyStack} />
<Drawer.Screen name="Login" component={LoginScreen} />
</Drawer.Navigator>
</NavigationContainer>
)
}
}
LginScreen.js
const LoginScreen = ({ navigation, propName }) => {
// const [bridge, setB] = useState(false)
return (
<SafeAreaView style={{ flex: 1, backgroundColor: '#376772' }}>
<TopHeader
onRefresh={() => fetch_crossings}
onMenuToggle={() => navigation.toggleDrawer()}
/>
<View style={{ flex: 1 }}>
<View
style={{
backgroundColor: '#fff',
margin: 10,
borderRadius: 5,
alignItems: 'center',
padding: 10,
paddingBottom: scale(20),
}}
>
<Avatar

size={'xlarge'}
overlayContainerStyle={{
backgroundColor: '#185a9d',
}}
icon={{
color: 'orange',
type: 'ionicon',
name: 'ios-log-in',
}}
/>
<Input
placeholder=" Email"
placeholderTextColor={'#292b2c'}
style={{ margin: 5 }}
errorStyle={{ color: '#d9534f' }}
leftIcon={<Icon name="mail" color="#292b2c" />}
errorMessage="Enter a valid Email"
/>
<Divider

<Input

secureTextEntry={true}
style={{ margin: 5 }}
errorStyle={{ color: '#d9534f' }}
leftIcon={<Icon name={'lock'} color="#292b2c" />}
errorMessage="Enter a valid Email"
/>
</View>
<View
style={{
backgroundColor: '#fff',
margin: 10,
marginTop: 0,
borderRadius: 5,
padding: 10,
}}
>
<Button
buttonStyle={{
margin: 10,
backgroundColor: '#5cb85c',
borderRadius: 4,
alignSelf: 'stretch',
}}
onPress={async () => {
try {
await AsyncStorage.setItem('is_admin', 'false')
**console.log(propName);** //<--Right HERE
navigation.navigate('Home')
} catch (error) {
console.log(error)
}
}}
icon={<Icon name="send" size={15} color="white" />}
iconRight
titleStyle={{ fontWeight: 'bold' }}
title="Submit "
/>
<Button
buttonStyle={{
margin: 10,
backgroundColor: '#d9534f',
borderRadius: 4,
alignSelf: 'stretch',
}}
onPress={() => {
navigation.navigate('Home')
}}
icon={<Icon name="close" size={15} color="white" />}
iconRight
titleStyle={{ fontWeight: 'bold' }}
title={'Close '}
/>
</View>
</View>
</SafeAreaView>
)
}
export default LoginScreen
Whenever I console.log(propName), it says that its undefined.
