Understanding React Navigation

What is React Navigation?

React Navigation is a JavaScript library for routing and navigation in applications. It facilitates the creation of fluid and dynamic navigation flows, allowing developers to manage navigation states effortlessly. Whether you’re developing an iOS mobile app or an Android app, React Navigation proves to be a versatile and efficient choice.

Key Features

Cross-Platform Compatibility: React Navigation excels in providing a consistent experience across various platforms, making it an ideal choice for cross-platform mobile app development services.
Customization: Tailor navigation to your application’s needs with extensive customization options. Define unique transitions, animations, and gestures to create a branded user experience.
Nested Navigation: Handle complex navigation scenarios with ease by implementing nested navigation structures. This feature proves beneficial in scenarios like building comprehensive dashboards or multi-level navigation.
Tab Navigation: Implement tab-based navigation effortlessly, a common pattern in mobile applications. It simplifies the creation and customization of tab-based interfaces.
Stack Navigation: Manage navigation using a stack-based approach, allowing smooth transitions between screens. This is particularly useful in scenarios where users move forward and backward through a linear flow.
Drawer Navigation: Integrate intuitive drawer navigation patterns for seamless access to various sections of your application. React Navigation simplifies the implementation of side menus for a polished user experience.

Integration Steps

Now, let’s delve into the integration steps to kickstart your journey with React Navigation:

Step 1: Installation

Begin by installing it using the following command:

npm install @react-navigation/native @react-navigation/stack

1	npm install @react-navigation/native @react-navigation/stack

Install dependencies in your react-native project by using the following command:

npm install react-native-screens react-native-safe-area-context

1	npm install react-native-screens react-native-safe-area-context

For running the application on ios run the following command:

npx pod-install ios

1	npx pod-install ios

Update the MainActivity.java file located at android/app/src/main/java/<your package name>/MainActivity.java to properly setup the app for android.

public class MainActivity extends ReactActivity {
  // ...
  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(null);
  }
  // ...
}

public class MainActivity extends ReactActivity {

// ...

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(null);

}

// ...

}

Step 2: Setup

Wrap the whole app in NavigationContainer and set up a basic navigation structure:

import * as React from 'react';
import { NavigationContainer } from '@react-navigation/native';

export default function App() {
  return (
    <NavigationContainer>
      {/* Rest of your app code */}
    </NavigationContainer>
  );
}

import * as React from 'react';

import { NavigationContainer } from '@react-navigation/native';

export default function App() {

return (

{/* Rest of your app code */}

</NavigationContainer>

);

}

Creating a native stack navigator

// In App.js in a new project
import * as React from 'react';
import { View, Text } from 'react-native';
import { NavigationContainer } from '@react-navigation/native';
import { createNativeStackNavigator } from '@react-navigation/native-stack';

function HomeScreen() {
  return (
    <View style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}>
      <Text>Home Screen</Text>
    </View>
  );
}

function DetailsScreen() {
 return (
   <View style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}>
     <Text>Details Screen</Text>
   </View>
 );
}

const Stack = createNativeStackNavigator();

function App() {
 return (
   <NavigationContainer>
     <Stack.Navigator initialRouteName="Home">
       <Stack.Screen name="Home" component={HomeScreen} />
       <Stack.Screen name="Details" component={DetailsScreen} />
     </Stack.Navigator>
   </NavigationContainer>
 );
}

export default App;

// In App.js in a new project

import * as React from 'react';

import { View, Text } from 'react-native';

import { NavigationContainer } from '@react-navigation/native';

import { createNativeStackNavigator } from '@react-navigation/native-stack';

function HomeScreen() {

return (

<Text>Home Screen</Text>

</View>

);

}

function DetailsScreen() {

return (

<Text>Details Screen</Text>

</View>

);

}

const Stack = createNativeStackNavigator();

function App() {

return (

<Stack.Navigator initialRouteName="Home">

<Stack.Screen name="Home" component={HomeScreen} />

<Stack.Screen name="Details" component={DetailsScreen} />

</Stack.Navigator>

</NavigationContainer>

);

}

export default App;

Step 3: Navigation Actions

Utilize navigation actions to navigate between screens programmatically. For instance, to navigate from the “Home” screen to the “Details” screen:

function HomeScreen({ navigation }) {
  return (
    <View style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}>
      <Text>Home Screen</Text>
      <Button title="Go to Details page" onPress={(() => navigation.navigate('Details'))}/>
    </View>
  );
}

function HomeScreen({ navigation }) {

return (

<Text>Home Screen</Text>

<Button title="Go to Details page" onPress={(() => navigation.navigate('Details'))}/>

</View>

);

}

Going Back

The top part of your app’s screen usually has a back button when you can go back to the previous screen. If there’s just one screen and nowhere to go back to, there won’t be a back button.
If you want to make the back button work without the user tapping it, you can make it happen with code using navigation.goBack().

function DetailsScreen({ navigation }) {
  return (
    <View style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}>
      <Text>Details Screen</Text>
      <Button title="Go to Home" onPress={() => navigation.navigate('Home')} />
      <Button title="Go back" onPress={() => navigation.goBack()} />
    </View>
  );
}

function DetailsScreen({ navigation }) {

return (

<Text>Details Screen</Text>

<Button title="Go to Home" onPress={() => navigation.navigate('Home')} />

<Button title="Go back" onPress={() => navigation.goBack()} />

</View>

);

}

Passing parameters to routes

This involves two steps:

To send information to another screen, use the navigation.navigate function with a second object parameter like this: navigation.navigate(‘RouteName’, { /* your information here */ }).
In the screen component, access the received information using route.params.

function HomeScreen({ navigation }) {
  return (
    <View style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}>
      <Text>Home Screen</Text>
      <Button
        title="Go to Details"
        onPress={() => {
          /* 1. Navigate to the Details route with params */
          navigation.navigate('Details', {
            itemId: 86,
            otherParam: 'anything you want here',
          });
        }}
      />
    </View>
  );
}

function DetailsScreen({ route, navigation }) {
  /* 2. Get the param */
  const { itemId, otherParam } = route.params;
  return (
    <View style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}>
      <Text>Details Screen</Text>
      <Text>itemId: {JSON.stringify(itemId)}</Text>
      <Text>otherParam: {JSON.stringify(otherParam)}</Text>
      <Button title="Go to Home" onPress={() => navigation.navigate('Home')} />
      <Button title="Go back" onPress={() => navigation.goBack()} />
    </View>
  );
}

function HomeScreen({ navigation }) {

return (

<Text>Home Screen</Text>

<Button

title="Go to Details"

onPress={() => {

/* 1. Navigate to the Details route with params */

navigation.navigate('Details', {

itemId: 86,

otherParam: 'anything you want here',

});

}}

</View>

);

}

function DetailsScreen({ route, navigation }) {

/* 2. Get the param */

const { itemId, otherParam } = route.params;

return (

<Text>Details Screen</Text>

<Text>itemId: {JSON.stringify(itemId)}</Text>

<Text>otherParam: {JSON.stringify(otherParam)}</Text>

<Button title="Go to Home" onPress={() => navigation.navigate('Home')} />

<Button title="Go back" onPress={() => navigation.goBack()} />

</View>

);

}

With these basic steps, you’ve set up a foundation for navigation in your React Native application using React Navigation.
