Hello I have a simple app and i want to add a drawer to him I use react-navigation 4x and use react-navigation-drawer
to implement Drawer in my app
I used it before sperate drawer in a single package and it's worked fine
but when I use the new package I got this error
Invariant Violation: Invariant Violation: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.
although I export my screen
here is Code
**navigator.js**
import React from 'react';
import {TouchableOpacity, View} from 'react-native';
import Icon from 'react-native-vector-icons';
import {createAppContainer, createSwitchNavigator} from 'react-navigation';
import {
createDrawerNavigator,
NavigationDrawerStructure,
} from 'react-navigation-drawer';
import {createStackNavigator} from 'react-navigation-stack';
import ForgetPassword from '../screens/ForgetPassword';
import Home from '../screens/Home';
import Splash from '../screens/Splash';
const AuthStackNavigator = createStackNavigator({
Authloading: {
screen: Splash,
navigationOptions: {
header: null,
},
},
});
const HomeStack = createStackNavigator({
HomeScreen: {
screen: Home,
navigationOptions: ({navigation}) => ({
title: 'Home',
headerLeft: <NavigationDrawerStructure navigationProps={navigation} />,
headerRight: (
<TouchableOpacity
onPress={() => navigation.navigate('Notifications')}
style={{margin: 10}}>
<Icon name="ios-notifications" size={28} color="#1DA1F2" />
</TouchableOpacity>
),
}),
},
});
const DrawerNavigator = createDrawerNavigator({
HomeDrawer: {
screen: HomeStack,
navigationOptions: {
drawerLabel: 'Home',
drawerIcon: () => <Icon name="ios-home" size={28} color="#0496FF" />,
},
},
});
const Navigations = createSwitchNavigator({
// Authloading: Splash,
Auth: AuthStackNavigator, // the Auth stack
App: DrawerNavigator, // the App stack,
});
const Navigator = createAppContainer(Navigations);
export default Navigator;
**Home.js**
//import liraries
import React, {Component} from 'react';
import {StyleSheet, Text, View} from 'react-native';
// create a component
class Home extends Component {
render() {
return (
<View style={styles.container}>
<Text>Home</Text>
</View>
);
}
}
//make this component available to the app
export default Home;
**App.js**
import React, {Component} from 'react';
import Navigator from './src/navigations/navigator';
class App extends Component {
render() {
return <Navigator />;
}
}
export default App;
Edit
i just think NavigationDrawerStructure it's exports from react-native-drawer so that's my bad :)
so here is the component name as NavigationDrawerStructure
//Navigation Drawer Structure for all screen
class NavigationDrawerStructure extends Component {
//Structure for the navigatin Drawer
toggleDrawer = () => {
//Props to open/close the drawer
this.props.navigationProps.toggleDrawer();
};
render() {
return (
<View style={{flexDirection: 'row'}}>
<TouchableOpacity onPress={this.toggleDrawer}>
<Icon
name="ios-menu"
size={40}
style={{margin: 10}}
color="#1DA1F2"
/>
</TouchableOpacity>
</View>
);
}
}
OR just add a button for a toggle in heder left inside Home stack like this
navigationOptions: ({navigation}) => ({
title: 'Home',
headerLeft: (
<TouchableOpacity onPress={() => navigation.toggleDrawer()}>
<Icon
name="ios-menu"
size={40}
style={{margin: 10}}
color="#1DA1F2"
/>
</TouchableOpacity>
)
})
