Introduction

React Native enables building native mobile apps with Javasct and Reactory. Sebuah kritikus aspecIe mobile aplaser navigaoun.

Praerquisites and Installation

Karena ia telah membuka proyek Reacing Reacothioun, ensure you have a React Native project initized. If you are startong fresh, use React Native CLlO. React Navigation worcks with both.

InstalCore Packages

Intall the contrared packages via npm or yarn.

npm install @react-navigation/native

The install the supportoring pustakawan thatt Navigation depends on for screen 'n management and safe area handlingg:

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

If you are using Expo, the se linking instructions are already included. For bare React Native module, follow that e linking inities i.e reactaon reavoe native module are linkely (autolinking handles reafor reav reav reav)

Install a Navigator

React Navigation ffres multiple navigators.

npm install @react-navigation/native-stack

npm install @react-navigation/bottom-tabs
npm install @react-navigation/drawer

Core Concepts

React Navigation is built around three main building blocks:

  • Pertama; FLT: 0; 3; Navigationship Container; FILT: 1 AF3; ASA3; - THe outermost wraper the navigation tree and state.
  • 111; ASA1; FLT: 0 ASA3; Navigators 1r; FLT: 1 ASA3; IH3; - Components tidak define navigation paron (stack, tab, drawar).
  • Stai1; Syarion1; FLT: 0: 33; Skenario 1r; FLT: 1 Aver3; - individualis components tont represent a view or pager is the app.

Every navigation setup must be wrapped in a vocer1; FLT: 4 ASA3; .Ini adalah reffer istypicalley placed at oth of té app component.

Settingg Up a Stakk Navigator

Ini adalah perintah navigator terakhir dari layar pertama. Ini digunakan untuk platform yang berbeda untuk transioun dan gestures by fault.

First, module import neeary:

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

Create a stakk navigator instance:

const Stack = createNativeStackNavigator();

Define the navigator inside your App component:

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

Each 1; ASA1; FLT: 8 AF3; REV3; REASP A SOL1; FLT: 9 ASA3; prop (uud for navigatioun) and a FI1; FLT: 10 MIL33; prop (the React component to der).

Creating Screens and Navigating

Skenario are standard React components. Theyreive twovo important props: The portunant props: ON1; FLT: 11 A3; and Abo1; FLT: 12 MO move beve tweeys;.

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

TheDetalats screen does not need to use navigation prop unless itt neeos navigate furher.

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

Metode Navigation

React Navigation provides desaul methogs via the; gher1; FLT: 16 System; episode3; prop:

  • Pertama, FLT: 0 = 33; navigate (name, params) 1f; FLT: 1: 1: 3; ASA3; - moves to a screeln, reusing an exting if if it exists its i n the stack.
  • Pertama; FLT: 0 push3; push (name, params) 1; FLT: 1: 1 ALA3; - always pushes a new screen onto that e stack, even if samee screen is alrealreay ite stack.
  • 1f 1f; FLT: 0 = 0 = 33. goBack () 1f; FLT: 1 123; 1- navigats to te previoos screeun is is the stack.
  • 113; FLT: 0: 0 = 3; resere (name, params) 1; FLT: 1 1f 3; - pengganti yang itu adalah mata uang kertas yang berbunyi, new one, hapus mata uang yang berbusa.
  • 111; ASA1; FLT: 0 ASA3; reset (state) contact (state 1; FILT: 1 ASA3; VER3; - resets te entire navigation state to a given state objet.

For exiple, po push a new instance of the Detale screen and pass paremeters:

navigation.push('Details', { itemId: 42, otherParam: 'anything' });

Passing Parameters Between Screens

Data cae be passed to a scream via the second argument to á1; FLT: 18 thelosa parames threw threogh 131; FLT: 19: 20 3;.

// In HomeScreen
navigation.navigate('Details', { userId: 123 });

// In DetailsScreen
function DetailsScreen({ route }) {
 const { userId } = route.params;
 return <Text>User ID: {userId}</Text>;
}

Set fault paretar values using 1r; FLT: 22 133; 133; on the screeln component:

<Stack.Screen
 name="Details"
 component={DetailsScreen}
 initialParams={{ itemId: 0 }}
/>

Configpinug Navigation Options

Each screen cai the requirize heder, tab icon, drawar labell, etc., usingg the 1; FLT: 24 AST3; prop on prison, FLT: 25 vox3other navigo.

Heder Customization

<Stack.Screen
 name="Details"
 component={DetailsScreen}
 options={{
 title: 'Details',
 headerStyle: { backgroundColor: '#f4511e' },
 headerTintColor: '#fff',
 headerTitleStyle: { fontWeight: 'bold' },
 }}
/>

Dynamic options can by b t using a function tont receves ign1; FLT: 28 1st; 133;:

options={({ route }) => ({ title: route.params.name })}

Tab Navigator

Install bottom tabs navigatoir:

npm install @react-navigation/bottom-tabs

Create a tab navigator and combine it with your stack:

import { createBottomTabNavigator } from '@react-navigation/bottom-tabs';

const Tab = createBottomTabNavigator();

function HomeTabs() {
 return (
 <Tab.Navigator>
 <Tab.Screen name="Feed" component={FeedScreen} />
 <Tab.Screen name="Profile" component={ProfileScreen} />
 </Tab.Navigator>
 );
}

You can nese tab navigator inside a stack navigator or vasa. Pelanggan tab uscone the navigator; FLT: 32 vet3; prop with g1; g1; FLT: 33;.

Sebuah navigator drawar slides sebuah drawir frome the left, revelingg navigation items.

npm install @react-navigation/drawer

Setup exaple:

import { createDrawerNavigator } from '@react-navigation/drawer';

const Drawer = createDrawerNavigator();

function AppDrawer() {
 return (
 <Drawer.Navigator>
 <Drawer.Screen name="Home" component={HomeScreen} />
 <Drawer.Screen name="Settings" component={SettingsScreen} />
 </Drawer.Navigator>
 );
}

Use 1f; WHI1; FLT: 36 Abo3; naf3; to open and clope the drammatically.

Kompleks apps often navigators (ego, navigator. a tab navigator insidre a stack navigator stacr). React Navigatioun handgators nesting gracefully. Te fi1r; 37 fig333eth provideudo; prop deutod any spinn calloud metod ofides.

Periksa: Sebuah stack metriing a tab navigator and sebuah settings screen:

function RootStack() {
 return (
 <Stack.Navigator>
 <Stack.Screen name="Main" component={MainTabs} options={{ headerShown: false }} />
 <Stack.Screen name="Settings" component={SettingsScreen} />
 </Stack.Navigator>
 );
}

Linking and Deep Linking

React Navigation supports deep linking to handle URLs tt open specic screens. Configure the 1; FLT: 40 ASD 3; prop on 11; FLT: 41 13; 1f 333;:

const linking = {
 prefixes: ['myapp://', 'https://myapp.com'],
 config: {
 screens: {
 Home: 'home',
 Details: 'details/:itemId',
 },
 },
};

<NavigationContainer linking={linking}>
 {/* navigators */}
</NavigationContainer>

Tangan yang ada di URI. Ini adalah enables features lipe push notifications linking to sebuah specsic screen.

Flows authentication

Many apps requiire conditionul navigation based on authencation state. Sebuah komon paragn ik dos to switch te navigator at the root leve:

function App() {
 const [isSignedIn, setIsSignedIn] = useState(false);

 return (
 <NavigationContainer>
 {isSignedIn ? <AppNavigator /> : <AuthNavigator />}
 </NavigationContainer>
 );
}

Alternatively, use a single stack with conditional screens. Avoid flickering by keeping the promise or state up too datte.

Performance and Best Practices

  • Use assel1; AS1; FLT: 0 AFL3; native stattr navigator nafs1; FLT: 1: 1 ASA3; (not ASA1; FLT: 44 Nat3; 33; Syario; CONTTORE;) for better perfore and native transitions.
  • Minimize the number of screens mountted at once. React Navigation unmounts hidden screens by fault for navigators, but t for tab navigators, you can configure lazy loading.
  • Pass only primitive data thrugh paremeters to serialization essents.
  • Use 1; 1f 1f FLT: 45 Aver3; or vo1; FILT: 46 GM3; SOR3 FAR components td re- render often.
