I'm developing a React Native app with TypeScript and using Firebase for data storage. In my app, I have a context provider (NatureRecordProvider) that should wrap two main screens, NatureRecordForm and RecordStorage. However, when I navigate to these screens, I encounter the following error in my web server:
Error Message:
enter image description here
The full error trace suggests that useNatureRecord is being used outside of the NatureRecordProvider, though I believe I've wrapped the necessary components with the provider.
Here’s a summary of my setup:
- Context Setup:
- NatureRecordProvider is defined in RecordContext.tsx and provides several functions (addEnvironmentalRecord, addBiologicalRecord, etc.) to manage records.
- useNatureRecord is a custom hook to access the context.
- Navigation Configuration:
- RecordNavigation component wraps NavigationContainer with NatureRecordProvider.
- Component Usage:
- NatureRecordForm and RecordStorage are both accessed via RecordNavigation.
Code Samples:
- RecordNavigation.tsx:
const RecordNavigation = () => { return (<NatureRecordProvider><NavigationContainer><Stack.Navigator initialRouteName="NatureRecordForm"><Stack.Screen name="NatureRecordForm" component={NatureRecordForm} /><Stack.Screen name="RecordStorage" component={RecordStorage} /></Stack.Navigator></NavigationContainer></NatureRecordProvider> );};

Troubleshooting Steps:
- Confirmed that NatureRecordProvider wraps NavigationContainer.
- Checked that useNatureRecord is only called within components under RecordNavigation.
Questions:
- Why am I receiving this error even though NatureRecordProvider appears to wrap the necessary components?
- Could this be related to the navigation structure or async data loading within the provider?
Any guidance on resolving this error would be greatly appreciated!
I expected the NatureRecordProvider context to provide data to all components within the navigation stack, as I wrapped the navigation stack in NatureRecordProvider. I anticipated that useNatureRecord would work within both NatureRecordForm and RecordStorage without error. However, instead, I encountered the error message: “useNatureRecord must be used within a NatureRecordProvider.”
