How do I implement authentication flow in React Navigation?

To implement authentication flow in React Navigation, you can use a combination of stack and tab navigators. Start by setting up your navigators and defining your screens for login, signup, and the main app.

Can you show me a code example for the login screen?

Sure! Here's a simple login screen example:

import React, { useState } from 'react';
import { View, TextInput, Button } from 'react-native';

const LoginScreen = ({ navigation }) => {
  const [email, setEmail] = useState('');
  const [password, setPassword] = useState('');

  const handleLogin = () => {
    // Handle login logic here
    navigation.navigate('Home');
  };

  return (
    <View>
      <TextInput placeholder="Email" value={email} onChangeText={setEmail} />
      <TextInput placeholder="Password" value={password} onChangeText={setPassword} secureTextEntry />
      <Button title="Login" onPress={handleLogin} />
    </View>
  );
};

export default LoginScreen;

What about handling user sessions?

You can manage user sessions using AsyncStorage to store the authentication token. Check the token on app startup to determine if the user is logged in.
