How can I handle errors in React Navigation on Android?

You can use error boundaries in your React components to catch errors in the rendering process. For React Navigation, wrap your navigators in an error boundary component.

Can you show me a code example of how to implement that?

Sure! Here's a simple example:

import React from 'react';
import { View, Text } from 'react-native';
import { NavigationContainer } from '@react-navigation/native';
import { createStackNavigator } from '@react-navigation/stack';

const Stack = createStackNavigator();

class ErrorBoundary extends React.Component {
  constructor(props) {
    super(props);
    this.state = { hasError: false };
  }

  static getDerivedStateFromError(error) {
    return { hasError: true };
  }

  componentDidCatch(error, errorInfo) {
    console.error('Error caught in ErrorBoundary:', error, errorInfo);
  }

  render() {
    if (this.state.hasError) {
      return <Text>Something went wrong!</Text>;
    }
    return this.props.children;
  }
}

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

This wraps your navigator in an error boundary.

What should I do if an error occurs?

If an error occurs, you can log it for debugging purposes and display a fallback UI to the user, as shown in the example.
