Debugging React Native: Screen Transition Causing State Loss in Cross-Platform App
I've been struggling with this for a few days now and could really use some help. I keep running into Building an application that needs to work seamlessly on both iOS and Android, I've encountered a perplexing issue with screen transitions. After switching between a couple of screens in my React Native app, the state of my components seems to reset unexpectedly. I suspect it has something to do with how I'm handling the navigation stack, but I'm not entirely sure. Here’s how I've set up the navigation using React Navigation v5: ```javascript import { NavigationContainer } from '@react-navigation/native'; import { createStackNavigator } from '@react-navigation/stack'; const Stack = createStackNavigator(); function App() { return ( <NavigationContainer> <Stack.Navigator> <Stack.Screen name="Home" component={HomeScreen} /> <Stack.Screen name="Details" component={DetailsScreen} /> </Stack.Navigator> </NavigationContainer> ); } ``` Within my `DetailsScreen`, I’m storing some data using React's `useState`: ```javascript const DetailsScreen = ({ route }) => { const [data, setData] = useState(route.params.data); const handleChange = () => { setData('New Data'); }; return ( <View> <Text>{data}</Text> <Button title="Change Data" onPress={handleChange} /> </View> ); }; ``` Navigating back to the `HomeScreen` and then returning to `DetailsScreen` causes the `data` to revert to its initial state from `route.params`. I’ve read about using `useFocusEffect` to persist state, but I'm not entirely convinced that’s the right approach for my scenario. Here’s what I’ve tried: - Keeping the state in a global context but that introduces complexity. - Storing state in Redux, but that felt like overkill for this situation. - Utilizing local storage to cache the state, which works but seems inefficient for user experience. What would be the best way to prevent state loss during navigation? Is there a recommended pattern for managing component state across transitions in React Native? Any insights would be greatly appreciated! Any examples would be super helpful. Any help would be greatly appreciated!
