 },
{
   InitialRouteName : 'Home',
   drawerWidth : 300,
   drawerPosition: 'left'
}
);
const AppContainer = createAppContainer(MyDrawerNavigator);

Main.js

//import liraries
import React, { Component } from 'react';
import { StyleSheet, View, Text, TouchableHighlight, Image } from 'react-native';

// create a component
class Main extends Component {
        static navigationOptions = {
        drawerLabel: 'Home',
        drawerIcon : () =>(
            <Image source ={require('../icons/home.png')}/>
        ),

            <TouchableHighlight onPress ={() => this.props.navigation.dispatch(DrawerActions.openDrawer())} style={styles.touchableHighlight} underlayColor={'rgba(0,0,0,0.8)'}>
            <Text style={styles.open}>OPEN</Text>

    color: 'purple'
},
});

//make this component available to the app
export default Main;

Other screens are just to display and hide the Drawer. Pls i need guidance am i missing anything?

Answer 1

This is a common issue showing up when alignItems: 'center' is applied to the container of a navigator. Remove it from App.js and it should work.

Answer 2

After removing alignItems: 'center' from app.js file, it worked. For some reason, react native does not show any error msg instead of white screen

Answer 3

Check to make sure you aren't wrapping your NavigationContainer with a SafeAreaView.

Answer 4

when follow doc https://docs.swmansion.com/react-native-gesture-handler/docs/2.1.1/#js

export default function App() {
  return <GestureHandlerRootView>{/* content */}</GestureHandlerRootView>;
}

like docs content you will need to pass { flex: 1 }. just pass style to it.

(actually I use react-native-reanimated@3, not need to use GestureHandlerRootView)

Answer 5

I got it to work now , i just made few Adjustments and changed few Links and all worked fine here. No more White screens.
