Swipe to open contacts screen in React Native

Question

I am using bottom navigation and when I navigate from dialer screen to contacts screen by swiping, at that time I want to open the contacts screen of my phone directly. Below I have shared the code of ContactComponent file and BottomNavigation file. I'm new to React Native so please help me. Thanks in advance.

ContactComponent.js

const ContactComponents = ({ navigation }) => {
 useEffect(() => {
   Linking.openURL("content://com.android.contacts/contacts")
  }, []);

 }
 export default ContactComponents

BottomNavigation.js

const Tab = createMaterialTopTabNavigator();
export default function BottomNavigation() {
return (
  <Tab.Navigator
  tabBarPosition='bottom'
  initialRouteName='Dialer'
  screenOptions={{ 
    tabBarLabelPosition: "beside-icon",
    //tabBarLabelStyle: { fontWeight: "700", fontSize: 15, color : 'white'},
    tabBarIconStyle: { display: "none" },
    tabBarStyle :{backgroundColor : bottomTabBarColor},
    tabBarIndicatorStyle : {position : 'relative', borderWidth : 2 , borderColor : bottomTabBarIndicatorColor}
    }}>
    <Tab.Screen 
      
      name="Messages" 
      component={MessageComponent} 
      options = {{
        tabBarLabel: ({focused, color, size}) => (
          <Text style={ [styles.textStyle, {color: focused ? focusedLabelColor : unfocusedLableColor , fontWeight : focused ? 'bold' : 'normal' }] }>Messages </Text>
        ),
      }}
    />


    <Tab.Screen 
        name="Last Ones" 
        component={LastOnesComponent} 
        options = {{
          tabBarLabel: ({focused, color, size}) => (
            <Text style={ [styles.textStyle, {color: focused ? focusedLabelColor : unfocusedLableColor , fontWeight : focused ? 'bold' : 'normal' }] }>Last Ones </Text>
          ),
        }}
    />

    <Tab.Screen 
        name="Dialer" 
        component={Dialpad} 
        options = {{
          tabBarLabel: ({focused, color, size}) => (
            <Text style={ [styles.textStyle, {color: focused ? focusedLabelColor : unfocusedLableColor , fontWeight : focused ? 'bold' : 'normal' }] }>Dialer </Text>
          ),
        }}
    />


    <Tab.Screen 
        name="Contacts" 
        component={ContactComponents} 
        options = {{
          tabBarLabel: ({focused, color, size}) => (
             //<View style={focused ?  styles.topTabLine : null}>
             <Text style={ [styles.textStyle, {color: focused ? focusedLabelColor : unfocusedLableColor , fontWeight : focused ? 'bold' : 'normal' }] }>Contacts </Text>
             //</View>
          ),
        }}
    />


  </Tab.Navigator>

For Android, you can open the Contacts app using native Linking in react-native.

const openContacts = () => {
  if (Platform.OS === 'android') {
    Linking.openURL('content://com.android.contacts/contacts');
  }
};

Now, if you want to open the contact screen when the dialer screen is focused, you can use the useFocusEffect hook in @react-navigation/native to do that.

In the screen where you want to navigate to the Contacts application, use this hook as shown.

import { useCallback } from 'react';
import { Linking, Platform } from 'react-native';
import { useFocusEffect } from '@react-navigation/native';

.
.
.

useFocusEffect(
  useCallback(() => {
    if (Platform.OS === 'android') {
      Linking.openURL('content://com.android.contacts/contacts');
    }
  }, [])
);

This is a snack for implementation
